Electronic Batch Record: Digital Batch Documentation Without Re-Entering Data

An electronic batch record allows you to create batch documentation while production is in progress, using data generated in ERP, MES, control systems, scanners and measurement devices. If you are a production director, you can expect less manual data re-entry, faster documentation closure and easier reconstruction of the history of a specific batch. However, an electronic form alone will not provide these benefits. You still need to determine where each piece of information comes from, which batch it should be linked to and when the system can take over its recording from a person.

An Electronic Batch Record, or EBR, is an electronic record of the execution of a specific production batch. Depending on the process, it may include materials used, subsequent operations, equipment, actual process parameters, inspection results, people performing particular activities, deviations and required approvals.

In batch manufacturing, such a record needs to be distinguished from the Master Batch Record. The MBR defines the approved way of manufacturing a product: the recipe, sequence of operations, required materials, parameters and inspections. An electronic batch record shows how a specific batch was actually produced according to those assumptions. Siemens describes EBR precisely as a record of actual data related to batch execution, including materials used, equipment, parameters, operators and process results.

ISA-88 also helps put the subject into context. Part 4 of the standard defines a Batch Production Record content model, meaning the data describing the execution of batch production. The model is intended to support the storage and exchange of such information and enable its later retrieval, analysis and reporting. However, it is not worth simplifying this relationship by saying that a BPR is a paper document and an EBR is its electronic equivalent. BPR is a concept describing a record of batch execution, whereas Electronic Batch Record is a term widely used for the electronic management of such a history in specific IT solutions.

For your manufacturing company, the technical consequence is more important. If a paper sheet is transferred into an application, but the operator still re-enters the temperature from the HMI, the material number from a label and the time from another system, the documentation has become electronic. The level of automation, however, remains limited because the employee still acts as the link between several data sources.

You will see the biggest change when information is recorded at the moment it is generated. An electronic batch record can be populated as subsequent operations are performed instead of being created after the end of a shift from forms, files and records left behind by different systems.

On the shop floor, this can look very ordinary. A scanner reads the batch number of the raw material being collected, the control system records process temperature and duration, ERP provides the production order number, and MES or the batch control system knows which operation is currently being performed. A result from a measurement device can also be captured automatically if the device makes the data available in an appropriate format. The operator should remain the source of information that genuinely requires human knowledge or a decision, such as explaining the cause of an unusual stoppage or assessing a particular event.

This is where part of the real labour savings comes from. If an employee reads a result from one screen and types it into another, the company creates an additional step in which an error can occur. Automatically transferring the value removes that step, but it does not guarantee the correctness of the source itself. An incorrectly configured PLC signal, a wrongly assigned raw-material batch or an incorrect process limit can all be recorded very accurately by an electronic batch record system. Automation helps reduce transcription errors and missing entries, but it does not replace data quality control.

It is easy to start a discussion about EBR by reviewing the functions available in MES systems. You can learn much more by taking one typical set of production documentation and checking the origin of every field it contains.

If a report contains a temperature value, the first step is to determine where that value is generated. If it is already stored in a PLC or SCADA system, a manual operator entry may be unnecessary. For a material batch number, it is worth checking whether the identifier can be obtained from WMS or a scanner. A comment concerning a non-conformance is different because the system does not know the cause of the event and needs information from a person. Such a review can be organised in a simple table:

The map above shows the difference between information created by a person and information merely re-entered by that person. Automating a human decision may be a mistake, while automating the mechanical transfer of a value usually makes much more sense.

Batch genealogy allows you to determine which raw-material batches were used to manufacture a product, which intermediate products were used along the way and which products received a given material batch. It is therefore a foundation of traceability, but it does not describe the entire course of production.

An electronic batch record uses these relationships and adds execution context. It shows the equipment, operation, parameters, inspection results, time and events associated with a specific batch.

Let us assume hypothetically that product batch P-240917 was manufactured from two raw-material batches. The material numbers were recorded during picking, the system knows which mixer was used in the process, and the control system provides the mixing time and temperature profile. Later, a quality inspection result is assigned to the same batch. The EBR should combine this information into one history instead of presenting it as separate datasets.

This is where one of the more important technical requirements appears. A value of “72.4°C” stored in a database is of little use if you do not know which machine it came from, when it was recorded, which operation it relates to and which batch was being processed at that time. Automatic batch production reporting therefore requires not only access to data, but also reliable context.

There is no such requirement. EBR describes a way of maintaining an electronic history of batch execution, not a specific class of software. Such a record can be created in MES, a batch control solution or another system responsible for managing the process and its documentation.

In many plants, however, MES becomes the place where these data can be connected in a meaningful way. The production order comes from ERP, material information comes from WMS, process parameters come from control systems, and inspection results come from quality systems. Simply collecting the information is still not enough because the system must know which batch and which operation each item refers to.

When choosing MES for batch production, the availability of an electronic batch record software module should be discussed at the beginning, not at the end, of the evaluation process. It is also worth checking how the system identifies the batch currently being produced, how it links process data to an operation, how it stores corrections and change history, and what happens if communication with a data source is lost.

You can also calculate how many fields operators will still have to complete manually after implementation. Two solutions offered as an electronic batch record system may behave very differently in this respect. One may replace paper with an electronic instruction and form, while another may obtain a substantial amount of data from systems and devices without requiring a person to enter it again.

Moving from paper to an EBR is not really a single step. At first, you can replace paper with an electronic form so that the system checks whether required fields are present and whether the data has the correct format. At this stage, however, most information is still entered by the operator.

The next level begins when the system uses data that already exists within the plant. It obtains information from ERP, scanners, devices and control systems, while the user fills in only those fields that require human judgement or responsibility. This is when EBR manufacturing starts to genuinely change reporting, because documentation becomes less dependent on manual re-entry.

The next stage is review by exception, meaning a review focused on events that do not meet predefined rules. This should not, however, be equated with automatic approval of every batch that proceeds correctly. The scope of such automation depends on the industry, the quality system, the reliability of data and the rules adopted for the specific process.

For a production director, a more useful question than simply whether the company has EBR is how much information in its batch record documentation is still being manually re-entered even though it already exists digitally. This immediately leads to the places where integration can reduce the amount of work performed solely for reporting purposes.

At this point, it is necessary to clarify what eliminating errors really means. An electronic batch record can reduce the need to re-enter selected values and enforce the completion of steps defined in the workflow. It does not, however, protect the company against an incorrect recipe, an invalid signal from a device, an incorrectly assigned batch or a wrongly configured process limit.

In regulated industries, additional requirements apply to the way electronic records are maintained. For the US market, 21 CFR Part 11 applies to certain records maintained electronically instead of records required by other FDA regulations. The agency refers to these underlying requirements as predicate rules. Part 11 itself is therefore not a regulation that requires a company to implement an Electronic Batch Record.

This distinction also matters outside pharmaceutical manufacturing. Requirements specific to regulated pharmaceutical production should not automatically be transferred to every plant producing in batches. The scope of batch record documentation, approvals, data integrity and validation should always be considered in relation to the specific product, industry and markets in which the product is sold.

Instead of starting with system presentations, choose a representative batch and identify the source of every field in its documentation. ERP, a controller, a scanner, a quality system, a measurement device or an operator? Then separate the data actually created by a person from the values that an employee merely reads in one place and enters in another.

The second step is to verify context. The mere presence of information in a system is not sufficient if it cannot be unambiguously linked to the correct batch and operation. A plant may have thousands of tags in SCADA and still require additional integration work before they can reliably supply an electronic batch record.

Finally, it is worth measuring the current process. Find out:

Your own data will give you a much better point of reference than general claims about percentage reductions in time.

Such an assessment requires production, quality, automation and IT. Production knows the actual course of operations, quality defines the rules for documentation and approval, automation engineers know which signals are available directly from devices, and IT assesses whether individual sources can be connected. Only by looking at the same batch from several perspectives can you define a reasonable scope for EBR.

Instead of starting by purchasing a module, you can analyse the flow of data through one typical batch and identify the places where documentation still requires manual intervention. Such an analysis will show where integration is needed, where the recording method should change and where operator involvement should remain.

If you want to quickly assess whether your plant is ready for an electronic batch record, take one set of batch documentation and classify every field as automatically retrieved, entered as a result of a human decision, or copied manually from another source. The third group is usually the best place to start automation because it consumes employee time without creating new information.

These terms should not be treated as simple synonyms. ISA-88 Part 4 defines a Batch Production Record as a data model describing batch execution. Electronic Batch Record is a term used in IT solutions for an electronically maintained batch history that may cover this data scope while also providing additional functions such as workflows, integrations and electronic approvals.

No. EBR can be implemented in different systems supporting batch processes. MES is a common choice because it can connect a production order with material, process and quality data, but the concept of Electronic Batch Record itself is not exclusively tied to MES.

Not all of them. It can reduce errors related to manual transcription, missing entries or skipping steps required by a workflow. It still depends on the correctness of source data, the configuration of the system and the proper assignment of information to the relevant batch and operation.

Batch genealogy shows the relationships between batches of materials, intermediate products and finished products. An Electronic Batch Record may contain this genealogy and, in addition, describe completed operations, equipment, actual process parameters, inspection results and events associated with a particular batch.

Start with one representative batch and its current documentation. Determine the source of every field, identify data that already exists digitally and check whether it can be reliably assigned to the correct batch and operation. Only then should you define the required integrations and system functions.
