Summary :
This SAP Note addresses common queries related to the ATP calculation discrepancies in R/3 - SD. It clarifies that transactions like MD04 and MMBE, while displaying available stocks, do not use ATP logic for their calculations, hence, their data should not be used for ATP confirmation. For issues like underconfirmation or unavailability despite visible stocks, the note points to the strict criteria of the ATP check across different nodes (plant, storage location). It also discusses possible misinterpretations due to system design, such as negative cumulated ATP indicating overconfirmation risks or issues due to obsolete lock entries in the ATPENQ table.
Key words :
batch main item remains confirmed, separately planned storage location, negative cumulated atp quantity, plant/storage location/batch, frequently asked questions, replenishment lead time, user manually increases, including batch functions, delivery proposal screen, negative cumulated atp
