Hi Varun,
I saw plenty of requirements in BPC when data is coming at the node level and should be assigned to some base member under that node.
This is standard BPC functionality to run DEFAULT.LGF after data load was done, but I'm not talking about it because it won't work in NItin's case.
I was talking about ROUTINE BADI which is quite different from CUSTOM_LOGIC BADI because it works before data is loaded to the Model.
