COMAC - which ATP check is done?

[Former Member]

Dear all.

We want to use transaction COMAC in order to have a list of order that can be produced today.

If we now run the COMAC we got a good looking list with orders that does not have status MSPT.

But unfortunately if we try to relase these orders sometimes we fail, as there are missing part. So it seems that we have different scope of checks in the COMAC and during the release.

How can we check which kind of check is done during COMAC?

Thanks and best regards, André

Hi,

1. Check the OPJK WITH The order type and also the Plant combination.

2. Inside this you can see a checking rule defined for the material avaivalability tab.

3. Based on this checking rule only the system will be doing the availabiltity chekc

Hi,

You can check which checking rule is assigned to the T-CODES in OMCP t-code

You can also check which checking rule is assigned during the creation of the order & Release of the Order in the t-code

Dear Rajanikanth.

Many thanks for the quik and helpfull answer. I checked the OMCP and found nothing maintained there for transaction COMAC. Do you know which rule is taken into account in this case?

Thanks and best regards, André

Hi Andre,

In OPJK, we can costumize business function 2 - Check availability during order release for availability check whether to carry or not.

So, even the order has check for the material availability.System is again check for the availability as per OPJK setting.
