The SAP error message UR481 indicates that a specific run (denoted as &1) cannot be undone until another run (denoted as &2) has been undone first. This typically occurs in the context of financial or logistics processes where certain operations are dependent on the sequence of runs or postings.
Cause: Dependency on Previous Runs: The run you are trying to undo (run &1) is dependent on the successful completion of another run (run &2). This means that the data or transactions processed in run &1 rely on the results of run &2. Data Integrity: SAP enforces this rule to maintain data integrity. Undoing a run that is dependent on another run could lead to inconsistencies in the data.
Solution: Identify the Runs: Determine what run &2 is and why it needs to be undone first. You can usually find this information in the error message or by checking the logs related to the runs. Undo Run
