Purge validation log

The purge validation log process deletes validation logs from the SCV validation log table. This process is implemented using the PURGE_VALIDATION_LOG program.

The PURGE_VALIDATION_LOG program considers these input parameters:

EXECUTIONS_TO_KEEP
The number of executions for which the validation log records must be maintained after deletion.
Note: By default, the value is set to 1.
SOURCE
The source system from which the planning data in the validation log is imported.

The PURGE_VALIDATION_LOG program deletes validation logs as follows:

  • Logs new log record.
  • Identifies the latest <EXECUTIONS_TO_KEEP> records for each separate table_name that is validated if the Source parameter is specified in the SZ_EXECUTION_TASK_LOG table.
  • Includes the execution_id task log record available in the PURGE_VALIDATION_LOG program in the <execution IDs to keep> list.
  • Deletes all records from the SZ_VALIDATION_LOG table where the execution_id value is not in the <execution IDs to keep> list.
  • Commits the changes upon successful deletion.
  • Completes the log record with the actual status.
