How To Fix 5A496 - No changes to data, periods undone

SAP Error Message - Details

• Message type: E = Error

• Message class: 5A - Basis Personnel Management

• Message number: 496

• Message text: No changes to data, periods undone

What causes this issue?

You have changed the period in the detail area without making changes
in an input field. If you have shortened the period (that is, if you
have entered a later start date or earlier end date), no change will be
made to the data displayed. In this way, unnecessary data records are
avoided.
When the period is next calculated, the old data is referenced, that
is, the old period is recreated.
If you, on the other hand, extend a period, all data within the
validity of the period is also extended. When the period is
recalculated, the changes are made.
If you change periods and input fields at the same time, data is always
changed.

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?

Change or delete at least one input field if you are shortening
periods.

• What is the cause and solution for SAP error message 5A496 - No changes to data, periods undone ?

  The SAP error message 5A496: No changes to data, periods undone typically occurs in the context of financial postings or adjustments in SAP, particularly when dealing with period-end closing activities. This error indicates that the system has detected that there are no changes to the data you are trying to process, and as a result, it has undone the periods.
