BPR stands for Batch Production Record. In pharmaceutical, biotechnology, food-supplement, and other regulated manufacturing industries, a BPR is the official record of how a specific batch was actually produced. It includes the operations performed, materials and equipment used, process parameters, quality-control results, operator signatures, and any deviations.
BPR is derived from an approved MPR or MBR template and is filled out during production. Therefore, BPR represents the actual production history, not the theoretical production instruction. Electronic Batch Record (EBR) systems are a digital, traceable, electronically signed, and audit trail-supported version of BPR. Centra's Electronic Batch Record (EBR) solution contributes to the more reliable and audit-ready management of batch production records.
The Basic Structure of the BPR Concept
What is BPR?
A BPR (Building Production Record) is a record created for a specific production batch and completed throughout the production process. It indicates which product was produced, with which batch number, on what date, with which equipment, by which operators, and under what process conditions. Therefore, from a GMP perspective, the BPR is the official proof of production for that batch.
Why is BPR officially recognized as a registered trademark?
Because BPR proves whether the product was actually manufactured according to the approved production instructions. In audits, complaint investigations, deviation investigations, and batch release processes, BPR is one of the key reference records.
What information does BPR include?
A BPR record may include product name, batch number, production date, MPR/MBR version used, raw material lots, weighing records, production steps, process parameters, IPC results, equipment information, cleanliness checks, operator signatures, QA/QC approvals, and deviation records.
Why should BPR content be complete?
Missing BPRs (Batch Registration Numbers) make it difficult to reliably verify the production process. For example, if a critical process value, electronic signature, weighing result, or QC approval is missing, it becomes difficult to make a reliable decision about batch conformity.
What is the difference between BPR and MPR?
MPR is the master production template that defines how production should be carried out. BPR is the actual record filled out during the production of a specific batch according to this template. MPR is a blank and approved instruction structure; BPR contains the actual records generated during production.
Brief summary of the difference.
The MPR (Master Production Record) answers the question "How will this product be manufactured?", while the BPR (Batch Production Record) provides proof of "How was this batch manufactured?". This distinction is important to avoid confusing the master record with the actual production record.
What is the relationship between BPR and MBR?
MBR, or Master Batch Record, is the main template for batch production. BPR, on the other hand, is the completed version of this template for a specific batch. While some companies use MBR and MPR interchangeably, BPR should always be considered the record created during the actual production process.
Is it possible to generate a BPR without an MBR?
From a GMP perspective, the BPR must be based on an approved master record or production instruction. Otherwise, it cannot be proven according to which approved standard the production was carried out. Therefore, the BPR is directly related to the MBR/MPR structure.
What is the difference between BPR and EBR?
BPR is the general name for a batch production record. This record can be kept on paper. EBR, on the other hand, is the digital version of BPR, created, managed, and stored in an electronic system. EBR provides additional advantages such as electronic signature, audit trail, timestamp, authorization, limit control, and automated reporting.
Could EBR replace BPR?
Yes. A properly validated and regulatory-compliant EBR system can be used as the official electronic batch production record in place of a paper BPR. However, this transition needs to be managed with change control, validation, and procedural updates.
Frequently Asked Questions About BPR and Electronic Batch Records
Why is BPR important from a GMP perspective?
The BPR (Batch Production Record) is the primary evidence that a product has been manufactured in accordance with approved procedures. During GMP audits, auditors can track the batch's production steps, signatures, quality control results, deviations, and release decisions via the BPR. Therefore, the BPR must be complete, legible, accurate, and traceable.
What does the auditor look for in the BPR?
The auditor may review whether records were kept on time, whether signatures are complete, the MBR/MPR version used, critical process parameters, deviation correlations, corrections, and QA/QC approvals.
How should deviations in BPR be shown?
If deviations from the procedure, limits, or expected process conditions occur during production, this must be clearly indicated in the BPR (Batch Production Record). It should be possible to trace the step at which the deviation occurred, when it was noticed, who recorded it, how its impact on product quality was assessed, and, if applicable, the CAPA linkage.
Would there be a problem if the deviation log was kept separate from the BPR?
Deviation can be managed in a separate quality system; however, its connection to the BPR (Balance of Preferences) must be clear. The auditor should be able to easily access the deviation record from the relevant batch record and from the deviation record to the batch.
What are the most common problems with paper-based BPR?
In paper BPR, missing signatures, illegible handwriting, incorrect dates, blank spaces, unexplained corrections, calculation errors, missing pages, and subsequently completed records are common. These issues pose risks to data integrity and auditing.
How does EBR reduce these problems?
EBR mitigates these risks through mandatory field control, electronic signature, audit trail, automated timestamping, limit control, and authorization. The system can halt progress if records are missing or critical approvals are incomplete.
How is BPR used in the batch release process?
Before releasing the batch, the QA team reviews the BPR (Basic Product Requirement). They evaluate whether production steps are complete, signatures are accurate, QC results are satisfactory, there are any obvious deviations, and critical process parameters are within limits. Finally, the authorized person or responsible manager makes the release decision.
Can a Batch Be Released with an Incomplete BPR?
Normally, no. If there are missing, inconsistent, or unexplained quality records, these issues must be completed or evaluated within the quality system before a batch release decision is made.
How does Centra EBR support BPR management?
Centra EBR can support the creation, completion, signing, review, and reporting of batch production records electronically by digitizing the BPR process. This makes batch records more traceable, consistent, and better prepared for auditing.
What should businesses do if they want to switch from BPR to EBR?
Businesses should first analyze existing BPR formats, recording errors, QA review times, critical data fields, and deviation correlations. Then, a pilot product or operation can be selected and an electronic batch record structure can be planned. To migrate BPR processes to EBR, Centra can be contacted via their information page.
