ATP Check for Stock Transport Orders from TLB

Hello Experts,

We have the following problem:

We have created a custom document type for Stock Transport Orders between two of our locations.

In case we create a STO in the R3 system manually an ATP check takes place which is correct.

The problem we face is, that when the order is created in APO TLB and transferred to R3 no ATP check is performed and the order is confirmed with it's original quantity despite the fact there is no enough available quantity on this particular date.

Has anyone an idea what we are missing?

Thank you in advance for your help

    Hi Georgi,

    In standard SAP the availability check will not happen for STOs which are created automatically , as described in the below link

    I would suggest you run any kind of Rescheduling of STOs to check the availability for STOs using Backorder processing in SCM or V_V2 in ECC after TLB run.

    HI Georgi,

    Note 1413545 explains it very well:

    VMI Scenario doesn't include an ATP Check in standard
    The standard VMI Scenario doesn't include an ATP check. VMI-Orders
    represent from the planning view no customer order but stock tansfer
    orders between two locations. If a VMI Order is created in APO, dates
    and quantities are calculated either by deployment or TLB. After
    transfering the VMI orders into the R/3 Execution system the APO results
    shouldn't be re-planned again. Therefore, VMI-Sales Order will be
    created as external confirmed TLB orders and sent back to APO 1:1 via
    key-completion without being checked again (no ATP-Check) and
    allocations are neither checked nor adjusted in standard. It is possible
    to use ATP Check while creating VMI Sales Orders in R/3 by implementing
    a modification in R/3 Inbound. This modification would remove the
    external confirmation status. Be aware of that you need to take care
    about special cases that could effect results.

    best regards,
