(Unable to change the order quantity value during save of sales order)

Thanks for your time guys. The issue is resolved.

SAP is not triggering the vbap user exit as the order quantity on screen is in structure RV45A.

There are two ways of resolving the issue.

1. Implement the SAP note #513342 - Quantity change and USEREXIT_MOVE_FIELD_TO_VBAP. But, it is SAP modification note.

2. Write the code in VBEP exit of MV45AFZZ. This user exit is called whenever the order quantity is changed. But, it is called multiple times in some cases. Hence, need to write code to limit our code execution only once e.g. maintain a global table with our quantity & uom. Check when the quantity and uom in our table is same as quantity on screen. If not, exit from user-exit.
