• What is the cause and solution for SAP error message /PLMI/ESD_BO021 - Constraint numbers of constraint &1 and constraint &2 are redundant. ?

  The SAP error message /PLMI/ESD_BO021 indicates that there are redundant constraint numbers in the context of a constraint-based planning scenario, typically within the SAP Advanced Planning and Optimization (APO) module or similar environments. This error arises when two constraints are defined in such a way that they do not provide additional value or differentiation in the planning process.
  
  Cause:
  The error is caused by the following scenarios:
  
  Redundant Constraints: Two or more constraints are defined that essentially enforce the same limitation or requirement on the planning process. This can happen if constraints are copied or if similar constraints are created without proper differentiation.
  Incorrect Configuration: The constraints may have been incorrectly configured, leading to overlaps in their definitions.
  Data Integrity Issues: There may be issues with the data integrity in the planning model, leading to the system recognizing constraints as redundant.
  
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review Constraints: Check the definitions of
