PP Experts please help (COMAC) - Urgent

Hi All,

I have a serious issue with coll. av. check as the standard SAP transaction COMAC is not helping me carry out av. check at operation level.

Eg:

Plant Stock for MtlF 3nos, MtlZ 4nos.

Wrk order - 1 for SubAssy-1

Crtd. on. - 25.1.08

Basic st dt. - 15.2.08

Opn 1 -> Execution Dt. 15.2.08 MtlA (2nos), MtlD(2nos)

Opn 2 -> Execution Dt. 12.3.08 MtlF (3nos), MtlZ(4nos)

Wrk order - 2 for SubAssy-2

Crtd. on. - 27.1.08

Basic st dt. - 01.3.08

Opn 1 -> Execution Dt. 01.3.08 MtlX (2nos), MtlR(2nos)

Opn 2 -> Execution Dt. 05.3.08 MtlF (3nos), MtlZ(4nos)

In the above example, when work order-1 is created & released, the av check is ok. But when i create work order-2, release & carry out coll. av. check MtlF & MtlZ is missing even though the need for these mtl's is earlier than that in work order-1. This is because the basic start date of the work order-1 is earlier than that of work order-2. I am unable to carry out the check based on operation execution date, but can only carry it out based on basic start date, which does not help my case.

I hope i have put across my problem clearly. I would like to know how i can overcome this shortcoming & resolve the issue?

Await inputs.
