• What is the cause and solution for SAP error message WER244 - Only an item field can be assigned to a compare parameter ?

  SAP Error Message:
  
  WER244 - Only an item field can be assigned to a compare parameter
  
  Cause:
  This error occurs when you try to assign a field that is not an item field (for example, a header field or a non-item related field) to a compare parameter in a workflow or a condition. In SAP, compare parameters are designed to work only with item-level fields (fields that belong to individual line items in documents like purchase orders, sales orders, etc.).
  
  Explanation:
  
  Compare parameters are used in workflows, conditions, or BRF+ rules to compare values at the item level.
  If you mistakenly assign a header field or a field that does not belong to the item structure, SAP throws this error.
  This is a design restriction to ensure logical consistency in comparisons.
  
  
  Solution:
  
  
  Check the field assignment:
  
  Verify that the field you are assigning to the compare parameter is indeed an item field.
  If you intended to compare header data, use a header parameter instead of a compare parameter.
  
  
  
  Use the correct parameter type:
  
  For header fields, use header parameters.
  For item fields, use compare parameters.
  
  
  
  Adjust your workflow or condition:
  
  Modify the workflow step or condition to use the correct field type.
  If you need to compare header data, create a header parameter or use a different approach.
  
  
  
  Review the data structure:
  
  Check the data dictionary or the structure of the business object to confirm which fields are item fields.
  
  
  
  
  Related Information:
  
  This error is common in SAP Business Workflow when defining conditions or rules.
  It can also appear in BRF+ (Business Rule Framework plus) when setting up rules involving document items.
  Refer to SAP documentation on workflow parameters and business object modeling for more details.
  SAP Note or community forums may provide examples of correct parameter assignments.
