Post GATP unconfirmed TAN line only.

Hi All,


After Availability check happened through GATP (RBA) the sales order line item in ECC with item category TAN is only remaining in Sales Order.

The line item is unconfirmed with 0 quantity, though sufficient stock is available in both ECC and APO system.


Same issue replication is not happening in our quality system (with same settings as in production)

In Production, the issue does not happen all the time.

Kindly help me understand the possible reasons and appropriate solution (if any), for above issue.

Note: Let me know if more info required.

    Hello Kunalesh,

    I think you're talking about VA02 ? How does it work when you enter a new line item ? Does it work as expected respecting the ATP ?

    On a high level it looks to me as an issue with missing SAP notes ? (or) some custom coding in your system. You should raise a ticket to SAP after replicating it.

    Thanks & Best Regards,

    Babu Kilari

      First you need to see if ATP check is happening properly, in ECC / GATP. Check by doing a manual ATP check on the line item in VA02 by clicking on Check Item Availability. It is very much possible that there is no substitution happening in your case and hence only TAN item, this can be because of multiple reasons. I can think of these:

      - ATP check integration model not active for your mat-plant combination and check is happening in ECC

      - ATP check happening in APO, but no RBA.

      - RBA happening but no condition records / rules maintained that meets the criteria.

      The best thing to do here would be to do online ATP check and see what is happening.

      Best Regards
