Archiving PLPO and PLAS tables only

Present Situation:

We have a custom developed program to maintain Task Lists.

In this development we copy a specific set of applicable operations

from groupcounter u201C00u201D into the newly created Task List (Last

groupcounter + 1) or when updating operations.


Above solution has caused tremendous data growth in the datasets PLPO

and PLAS; 2,7 Mj records PLAS entries and 2,9 Mj. PLPO entries.

This data growth is in some cases causing run-time errors on some


Solution requested:

Although 2,2 Mj. Out of 2,7 Mj PLAS entries are marked for deletion, none of the PLPO entries have a deletion mark. Joined Task Lists in PLKO are still active.

SAP archiving (PM_PLAN) is not capable of deleting inactive operations.

Archiving can only be done on complete Task Lists.

We are looking for a way to clean the amount of records in PLPO and PLAS tables, perhaps a customized copy of PM_PLAN in AOBJ will do the trick but we lack experience on that subject.

Please advise on how to do so.


SAP's answer:

Dear Customer,

Unfortunately this is the standard behaviour, all task lists must

be fully completed before archiving can be performed.

Thank you for contacting SAP Active Global Support.
