• What is the cause and solution for SAP error message RSPLS137 - Aggregationlevel &1: Unitfields &2 is not a keyfield ?

  The SAP error message RSPLS137 indicates that there is an issue with the aggregation level in a SAP BW (Business Warehouse) environment. Specifically, it states that a unit field specified in the aggregation level is not defined as a key field. This can occur when you are trying to create or modify an aggregation level that includes unit fields that are not set up correctly.
  Cause:
  
  Non-Key Field: The unit field specified in the aggregation level is not defined as a key field in the InfoObject definition. In BW, key fields are necessary for aggregation and reporting purposes.
  Incorrect Configuration: The aggregation level may have been configured incorrectly, leading to the inclusion of non-key fields.
  Data Model Changes: Changes in the underlying data model or InfoObjects may have led to the unit field being removed or altered.
  
  Solution:
  
  
  Check InfoObject Definition:
  
  Go to the InfoObject maintenance transaction (e.g., RSA1) and check the definition of the unit field. Ensure that it is marked as a key field.
  If it is not a key field, you may need to adjust the InfoObject settings to include it as a key field, if appropriate.
  
  
  
  Modify Aggregation Level:
  
  Open the aggregation level in the BW modeling tools.
  Remove the unit field from the aggregation level if it is not necessary or replace it with a valid key field.
  Save and activate the changes.
  
  
  
  Recreate Aggregation Level:
  
  If the aggregation level is complex or if you are unsure about the changes, consider recreating the aggregation level from scratch, ensuring that only key fields are included.
  
  
  
  Check Dependencies:
  
  Ensure that there are no dependencies or other objects that rely on the aggregation level that may be affected by the changes.
  
  
  
  Transport Changes:
  
  If you are working in a development environment, ensure that any changes are transported to the appropriate environments (e.g., QA, Production) after testing.
  
  
  
  Related Information:
