Data Ageing - What to do, if Time Selection Partitioning goes wrong

dear all

after creating a wrong partitioning spec in Data Ageing - Tx DAGPTC.

i found it impossible to immediately revert back to the state i had, prior to the mistake.

this is a test system, so no real damage done, however, in my attempts to find an answer/procedure, i found nothing, so if anyone can point me in a direct, i would be most grateful.

please dont just reference the administration guide.

what i am looking for, would be something like the syntax to merge a time partition, or undo a command, or something.

note: this problem has nothing to do with data aging runs, nor the undo functionality, as it is prior to any runs at all.

any help please

thanks
