SAP info structure S012
There is one requirement in the MM side is to calculate the Delivery time variance in the infostructure S012.
In the standard system,
Delivery time variance = Planned delivery date - GR date.
But the requirement is
Delivery time variance = Planned delivery date - Excise Invoice date
Since we can not change the standard routines and also can not include our own routines then how i can achive the above mentioned requirement.
Is there any other way to do it.
I am new to this infostructure.
