Jitesh, thanks for your inputs. I checked both the notes but sorry to say they did not help much.
Let me explain the situation in detail. We have R/3 integrated with SCM. When a order quantity is changed along with requested delivery date at header level in VA02 then it works fine( MAD is getting updated to VBBE along with new quantity). But if I change requested delivery date at header level and do not change quantity then its not generating the requirement. I checked at the back end the internal table XVBBE and YVBBE are not getting filled so no update to VBBE table.
Just wanted to know if their is any config or some setting to make sure system always generate requirement even though if its same.
