Characteristics based ATP check results in overconfirmation.

Dear Experts,

We are dealing with the following problem: a characteristics based ATP check in SCM (e.g. ATP check on Length Class, Quality Grade), based on a sales order in ECC, as well as an ATP simulation with characteristics in SCM itself results in higher confirmation quantities than expected based on the actual stock quantities in combination with characteristics of underlying batches.

When a confirmed sales order is saved at ECC side the following consequences are shown at SCM side:

- Negative ATP quantities at Quantities tab in Product View

- Despite earlier confirmation there are no receipts pegged to the requirement resulting from the sales order (no entry at Pegging Overview tab in Product View)

Our questions:

- Why do we get negative ATP quantities?

- Why is the sales order confirmed when there is no stock with required characteristics available?

FYI: We have the following installation:

- SAP ECC 6.0 Industry Solution Discrete Industry & Mill Products (IS DIMP)

- SAP SCM 5.0

Regards,

APOtester

    Issue was solved by deactivating Enhanced Confirmation Logic in SCM customizing via APO --> Global ATP --> Product Availability Check --> Maintain Check Control. Enhanced Confirmation Logic should only be applied in situations where product allocation is active.
