Summary :
When creating or modifying a sales order item in SAP, a rule-based availability check via APO prompts the generation of sub-items, which are intended for sourcing. Despite these sourcing main items not requiring confirmation, an erroneous system message (V1601) stating "Item has no open quantity - Check fixed quantity ID" is triggered. This issue arises when the fixed quantity indicator is set, either through custom configuration for a specific sales area or manually on the scheduling screen. The solution to this problem involves program modifications detailed in SAP Notes, with prerequisite adherence to Notes 151153 and 179948 for respective SAP releases.
Key words :
open quantity - check fixed quantity id, rules-based availability check, rule-based availability check, additional key words v1601, system issues message v1601, fixed quantity indicator, = sourcing main item, sourcing main item, sourcing main items, apo = advanced planner
