Hello,
I am not sure why you would want to create a custom archive object for this table? Here is information from the SAP Data Management Guide for maintain table TST03:
Report RSPO1043 enables continuous monitoring of inconsistent spool objects (example: no entries in TST01 but entries in TST03 for a selected spool are available). Just as in RSPO0043, the write locks are analyzed and, if necessary, deleted. In contrast to report RSPO0043, report RSPO1043 can run parallel to the other activities in the background. To do this, the report must run daily. See also SAP Notes: 98065 (SAP_APPL 40A - 604): Spool consistency check with RSPO1043 as of 4.0A 1748033 (SAP_BASIS 46C – 740): RSPO1043 does not delete all inconsistencies Important recommendation: Please ensure that report RSPO1043 is replacing the former report RSPO0043. Please makes sure that you reschedule your jobs with the new report name.
Hope this helps. Best Regards, Karin Tillotson
