Symptoms

On : 12.2.5 version, Quality Management Samples

After creation of the pending lot, when the customer releases the Batch Step (note that 'Lot optional on Sample' checkbox is checked for the Specification Validity Rule ), the customer waits for the automatic execution of concurrent Workflow Background Process. After that, system creates a WIP Quality Sample without Lot Number.

Field "GMDQSMPL.WIP_LOT_NO" field is protected for automatically created samples, so using a personalisation, the customer has enabled the "GMDQSMPL.WIP_LOT_NO" field.  However, when trying to save the sample, the system is giving a message:

"Changes to this field may require a new Specification. Therefore the chosen Specification has been cleared ".

The customer needs to assign a Lot Number to all WIP Quality Samples without the error message forcing a change of  specification

5. Go to the samples form and open the created quality Sample and try to change the Lot Number (which has been un-protected by a personalisation )

6. System shows error "Change to this field may require a new specification. Therefore the chosen Specification has been cleared"



BUSINESS IMPACT
