• What is the cause and solution for SAP error message WRF_CHAR_VAL078 - Customer fields must be processed uniformly for each characteristic type ?

  SAP Error Message:
  
  WRF_CHAR_VAL078 – Customer fields must be processed uniformly for each characteristic type
  
  Cause
  This error occurs in SAP Variant Configuration or Classification when there is an inconsistency in how customer-specific fields (customer fields) are handled for a particular characteristic type. Specifically, the system expects that all customer fields related to a characteristic type are processed in a uniform manner, but it detects a mismatch or inconsistency.
  In more detail:
  
  Each characteristic type (e.g., CHAR, NUM, DATE) can have associated customer fields (additional fields defined by the customer).
  These customer fields must be processed consistently — for example, all must be processed as input fields or all as output fields.
  If some customer fields for a characteristic type are processed differently (e.g., some as input, others as output), the system raises this error.
  This inconsistency can arise due to incorrect configuration in the customer fields setup or in the processing logic (e.g., in user exits, BAdIs, or configuration tables).
  
  
  When does it occur?
  
  During configuration or classification processing.
  When saving or validating characteristics with customer fields.
  During variant configuration or classification data processing where customer fields are involved.
  
  
  Solution
  
  
  Check Customer Field Configuration:
  
  Go to transaction CT04 (Characteristics) and review the characteristic type.
  Check the customer fields assigned to this characteristic type.
  Ensure that all customer fields for this characteristic type are configured to be processed uniformly (e.g., all as input fields or all as output fields).
  
  
  
  Review Processing Logic:
  
  If you have custom code (user exits, BAdIs, or enhancements) that processes customer fields, verify that the processing is consistent for all customer fields of the same characteristic type.
  Make sure that the logic does not treat some customer fields differently than others for the same characteristic type.
  
  
  
  Check Configuration Tables:
  
  Review any relevant configuration tables or customizing settings related to customer fields and characteristic types.
  Ensure that the settings do not contradict each other.

  Additional Tips:
  
  Uniform processing means that if a characteristic type has multiple customer fields, all must be treated the same way in terms of input/output and processing.
  If you recently added or changed customer fields, verify that the changes are consistent.
  Test changes in a development or sandbox system before transporting to production.
