  The SAP error message PPEBAL136 indicates that there is a contradiction in the planned line assignment for a production line in the context of line balancing. This typically occurs in the Production Planning and Detailed Scheduling (PP/DS) module when the system detects inconsistencies between the planned line assignments and the line balance relationships defined in the system.
  Cause:
  The error can arise from several scenarios, including:
  
  Inconsistent Line Assignments: The planned assignments for work centers or production lines do not match the defined relationships in the line balancing configuration.
  Incorrect Configuration: The line balancing setup may not be correctly configured, leading to mismatches between the expected and actual assignments.
  Changes in Production Orders: If production orders are modified or if there are changes in the routing or work center assignments, it can lead to inconsistencies.
  Data Integrity Issues: There may be issues with master data, such as incorrect work center definitions or routing information.
