I did the test for top-down-distribution in account based COPA and followed three articles. It did not work.
Please give me some point to do KE28 successfully.
I give my step and TDD variant Setup below:
1. I check which line item I want to distribution, and I want to distribute customer and employee.
2. Create my variance tt98. In processing instruction, customer and employee is distribution level, the other is copy value.
3. In selection criteria, I give product, company and based selection cost element.
4. Then choose value field and save variance.
5. Got the fail massege.
