Hi,
The standard transformation logic for these 2 KFs should be at Group 3 level. There are 2 ways to resolve this.
1. Remove the transformations logic from the Standard group:- Remove the source fields and make it no transformation in Standard group.
2. Re-migrate the 3.x flow to 7.x
Also, another way to do is by following LSA architecture, the calculation for these KFs are done at individual routine level.
Hope this helps.
Regards.
