Hi,
As Rachel and I are trying to point out, it is not really a good idea to get these two critical fields for multiple modules into classification.
There are too many critical moving parts. These fields are used by FI / CO a lot in their transactions. You dont want to be building a separate and redundant Classification System unless there is a real need.
Assuming that you are not doing this for your learning and it is a real requirement, my question is what is the real Business Requirement for this ? What is the rationale for them asking this when the fields are available in SD/MM and CO ? Are the FI / CO / MM / SD Team in the loop on this ?
Thanks.
