I am working on quota arrangement when ever i create PO or purchase requisition allocated quantity is not updating any insight please.
Have you checked the "Quota Arrangement Usage Indicator" in the Material Master Purchasing and MRP 1 view. Kindly check the QA Usage indicator in SPRO- MM- Purchasing -QA-Define QA Usage
You can decide which all elements are included in a particular QA Usage Indicator.
QA Usage 1
PO : INCLUDE
SA Schedule Lines :INCLUDE
Planned Order : DO NOT CONSIDER
Purchase Requisition: DO NOT CONSIDER
This QA Usage indicator, when entered in a material master, will entail that whenever a PO or SA Schedule lines( only manual SA Schedule lines) are created, the allocated quantity in MEQ1 will be updated. Purchase Requisitions & Planned Orders will not be considered for allocated quantity.
Kindly recheck the QA usage indicator in the Material master and see the corresponding settings in SPRO.
Hope this helps.
