• What is the cause and solution for SAP error message APS_CKE_PARSER091 - You canÆt use a Dimension as primary data source for a Cube ?

  The SAP error message APS_CKE_PARSER091, which states "You can’t use a Dimension as primary data source for a Cube," typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when you are trying to create or modify a cube and have mistakenly set a dimension as the primary data source.
  Cause:
  
  Incorrect Data Source Configuration: The primary data source for a cube must be a fact table or a data source that contains transactional data. Dimensions are meant to provide context to the data but do not contain the actual transactional data needed for a cube.
  Modeling Error: During the modeling process, a dimension might have been incorrectly selected as the primary data source instead of a fact table.
  
  Solution:
  
  
  Check Data Source Configuration: 
  
  Open the cube in the modeling tool (e.g., SAP BW Modeling Tools or SAP HANA Studio).
  Verify the data source settings and ensure that a fact table is selected as the primary data source.
  If a dimension is currently set as the primary data source, remove it and replace it with the appropriate fact table.
  
  
  
  Review Data Model:
  
  Ensure that your data model is correctly designed, with clear distinctions between fact tables and dimensions.
  If necessary, create a new cube or modify the existing one to ensure that the primary data source is a fact table.
  
  
  
  Revalidate the Model:
  
  After making the necessary changes, revalidate the model to ensure that there are no further errors.
  
  
  
  Related Information:
  
  Understanding Dimensions and Fact Tables: In data warehousing, dimensions are used to describe the data (e.g., time, geography, product), while fact tables contain the measurable, quantitative data (e.g., sales amounts, quantities sold).
  SAP Documentation: Refer to SAP's official documentation for guidelines on data modeling in BW or HANA, which provides best practices for setting up cubes and dimensions.
  SAP Community and Forums: If you continue to face issues, consider reaching out to the SAP Community or forums where other users may have encountered similar problems.
  
  By ensuring that the correct data sources are used in your cube design, you can avoid this error and successfully implement your data model.
