Deleting the profitability segment will lead to inconsistent data

What causes this issue?

You deleted the assignment to a profitability segment and have
activated account-based Profitability Analysis and/or incoming sales
orders. If account-based Profitability Analysis is active, this makes
it impossible to post costs from a goods issue to Profitability
Analysis. It is therefore not possible to reconcile FI and CO-PA.
If incoming sales orders is active, it is not possible to transfer the
sales orders to Profitability Analysis.

System Response

Deleting the profitability segment leads to inconsistencies in the data
in Profitability Analysis. The profitability segment is displayed in
the incompletion log for the sales order.

How to fix this error?

Make an assignment to a profitability segment.
