Summary :
During an APO rules-based availability check within SAP, users face limitations with alternative item categories in sales orders. The system defaults to TAN (standard item) for new sales items in specific order and material category types, with an option to manually input alternative categories like TANN (Free-of-charge item). However, in an ATP context, the system forces the item category to TAPA (sourcing main item), overriding manual inputs and generating subitems in TAN or ALES, incompatible with the requested TANN. SAP suggests implementing program adjustments and utilizing transaction settings (0VVW, VOV7, VOV4) to align item categories accurately for such scenarios, including a sourcing reset via 'APO0' and custom configurations to respect manual category inputs and ensure proper system behavior during ATP checks.
