Hi,
While creating the contract in the line item one field product hierarchy is a mandatory field.In our project we maintain upto 3rd level of product hierarchy but if user maintain upto first level only in the sales document system is not throwing an error while saving the contract.Now through user exit we want to throw an error message if product hierarchy field is not maintained upto 3rd level.
Anybody please tell which user exit shall i use or in which user exit VBAP table in transaction VA41 & VA42 hits?
I gone through IMG documenation in SD--User exit but not getting clarity.
Regards,
SATYA
