3797827 - aATP Product Availability Check: Different confirmation dates between single line item and group (header) for sales orders with delivery groups

• In sales orders with multiple items and aATP enabled, users observe different confirmed delivery dates when comparing group-level (header) aATP checks with single line item checks. 
• The scenario is tested in SAP Fiori apps "Create Sales Order" (VA01)  and "Change Sales Order" (VA02) , with detailed results reviewed in the RACR Overview. 
• When running a group check for all items, some items show different confirmation dates than when running checks for individual items one by one. 
• Users may suspect a defect in RACR or the availability check functionality due to these differences. 
• The behavior is seen when items belong to one delivery group, where a common delivery date is applied at group level.

• Product:                               Advanced Available-to-Promise (aATP) and Product Availability Check (ATP). 
• Application area/component: CA-ATP (PAC).
