How To Fix 3G303 - Supplemental (sequence no.&1) has already been evaluated in run &2

3G303 - Overview

• Message type: E = Error

• Message class: 3G - Payroll: International

• Message number: 303

• Message text: Supplemental (sequence no.&1) has already been evaluated in run &2

What causes this issue?

The employee was skipped because at least one supplemental result has
already been evaluated live for posting with the run PP &V2&. The
supplemental result (payroll result with payroll type 'S') that has
already been evaluated live has the sequence number &v1&.
This payroll result has either already been evaluated with the
corresponding result of the regular period, or it has been evaluated
individually.
If at least one supplemental result or the regular result has already
been evaluated individually, all current payroll results of the employee
must be evaluated by posting individually for this payroll period. For
this reason, you should always evaluate all supplemental results
together with the result from the regular payroll period.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

If you have not posted the evaluation that has already been performed
productively, and the employee should therefore be evaluated again,
delete the posting run PP &V2& that has already been performed.
If you want to repeat the evaluation as a simulation, do not create a
live posting run. You should create a simulation run.

  A supplemental sequence number (e.g., for payroll or other evaluations) is being processed again, but it has already been evaluated in a previous run.
  There may be an attempt to reprocess or re-evaluate a sequence that is not allowed due to business rules or system constraints.
  
  
  Solution:
  To resolve this error, consider the following steps:
  
  
  Check the Sequence Number: Verify the sequence number mentioned in the error message. Ensure that it is indeed meant to be evaluated again. If it has already been processed, you may not need to evaluate it again.
