Follow one batch through the record

A batch record describes what happened during a particular manufacturing event. A master instruction describes what should happen. Keeping those records distinct helps a reviewer compare the planned process with the materials, observations and decisions recorded on the day.

The HPRA GMP guidance directory provides its current manufacturing guidance. The February 2026 guide addresses production, deviations, finished products and documentation. It supplements the relevant standard and does not reproduce all of it. For Great Britain, the government guidance describes GMP and the importance of manufacturing documentation. Neither source makes a generic spreadsheet a complete quality system.

Give the event an identity

The synthetic example uses batch SAMPLE-B01 for fictional Product A, product revision 2. The master instruction is MI-A revision 4. Those references belong in the event header before the material and process entries.

The example contains no recipe, processing temperatures, formulation percentages or release specifications. Real instructions, limits and checks must come from the controlled process for the actual product.

Link the material lots

The materials sheet records fictional material M-A from supplier lot LOT-A17 and packaging P-A from LOT-P08. The material identity and supplier document are separate references. A supplier document without a lot link would leave a traceability question open.

For a real event, record the planned and actual quantities with their units using the approved instructions. In this example the quantities are deliberately absent. The record therefore cannot show reconciliation or completion.

Capture the process observations

The events sheet links the manufacturing event to its instruction and equipment references. One synthetic entry records that an equipment-status reference has not been located. It does not invent a satisfactory result or overwrite the missing check with a tick.

An observation should lead to a traceable deviation or question where needed. Record who observed it, when, the relevant instruction, what evidence is attached and who will decide the next step. A retrospective note should retain its actual recording date under the business's document-control process.

Keep checks and release separate

The example's review sheet has an open deviation and no authorised release decision. Its status remains Hold. Finishing the data-entry fields does not release the batch.

A real record should connect the relevant results and disposition to the person authorised under the business's procedures. A missing result, an unexplained discrepancy or a changed process needs the appropriate investigation and decision. The organiser does not supply that judgement.

Trace forwards as well as backwards

Connect the batch reference to the packaging/artwork revision and the relevant stock or distribution record. That makes it possible to ask which material lot entered the event and where the resulting stock went. T05 provides the linked blank sheets and the deliberately incomplete example. Keep the product specification, manufacturing evidence and specialist product review connected while preserving their different purposes.
