• What is the cause and solution for SAP error message WER084 - Impossible add rule because it uses a different structure (&1) ?

  SAP Error Message:
  WER084 - Impossible add rule because it uses a different structure (&1)
  
  
  Cause:
  This error occurs in SAP Workflow when you try to add a rule to a container element, but the rule uses a different data structure than the container element expects. In other words, the data type or structure of the rule's output does not match the data type or structure of the container element to which you are trying to assign it.
  For example, if the container element is defined as a structure ZSTRUCT_A, and the rule returns a structure ZSTRUCT_B, SAP will raise this error because the structures are incompatible.
  
  Explanation:
  
  Workflow container elements have defined data types (structures, tables, elementary types).
  Rules used to fill or assign values to these container elements must return data of the same type.
  If the rule returns a different structure or data type, SAP cannot assign it, hence the error.
  
  
  
  Solution:
  
  
  Check the container element's data
