KAFF001 - Details

• The SAP error message KAFF001 indicates that there is an issue with the COEP (Controlling Document Line Items) table, specifically related to the fields PFKBER (Functional Area), PGEBER (Cost Center), or PGRANT_NBR (Grant Number). The error suggests that these fields are filled while the PAROB (Profitability Segment) field is empty, which is not allowed according to the structure of the COEP table.
  
  Cause:
  
  Data Inconsistency: The error typically arises when there is a mismatch in the data being posted to the COEP table. If the profitability segment (PAROB) is not populated while other fields are filled, it indicates that the data does not conform to the expected structure.
  
  Configuration Issues: There may be configuration settings in the Controlling (CO) module that are not aligned with the business processes or the data being entered.
  Missing Master Data: The profitability segment might not be properly defined or linked to the cost center or functional area in
