• Message number: 463

• Message text: Retroactive payroll run back to &1 not possible for person &2

What causes this issue?

You have changed the financing details of person &v2& so that they take
effect retroactively.
This means that the payroll results posted to the old donor budget
structure element will be canceled back to &1, and posted to the new
donor budget structure element.
However, the retroactive accounting date (&v1) is earlier than the
<DS:DE.PRRDT> personal earliest possible retroactive accounting date
</> of person &v2&.

System Response

Unable to perform retroactive accounting run back to &1.

How to fix this error?

You have two options:
Change the personal earliest possible retroactive accounting date to
&v1& in the <ls>Payroll Status</> infotype of person &v2&. Before you
do this, however, always ask yourself why the original earliest
personal retroactive accounting date was defined as it was.
Only change the <ls>financing assignment</> as of &v1&. This will mean
that there will be no conflicts with the earliest personal retroactive
accounting date defined for person &v2&,

H1463 - Details

• The SAP error message H1463 indicates that a retroactive payroll run cannot be performed for a specific employee (person &2) back to a specified date (&1).

  Data Inconsistencies: There may be inconsistencies or missing data in the employee's master data or payroll results that prevent the retroactive payroll from being processed.
