• What is the cause and solution for SAP error message RSDODSO165 - DataStore object &1 (master data check) must not contain char. &2 in key ?

  The SAP error message RSDODSO165 indicates that there is an issue with a DataStore Object (DSO) in SAP BW (Business Warehouse) where a character (field) that is part of the key structure is not allowed in the master data check. This typically occurs when the DSO is configured to use certain characteristics as keys, and one of those characteristics is not suitable for the master data.
  Cause:
  
  Key Definition Issue: The DSO is defined with a key that includes a characteristic that is not allowed for master data. In SAP BW, certain characteristics are expected to be used as keys in specific contexts, and if a characteristic is not defined correctly, it can lead to this error.
  Data Model Misconfiguration: The DSO may be incorrectly configured in terms of its data model, leading to the inclusion of a characteristic that should not be part of the key.
  Master Data vs. Transaction Data: The error may arise if there is confusion between master data and transaction data. Certain characteristics are meant to be used only in transaction data and not in master data.
  
  Solution:
  
  Review DSO Configuration: Check the configuration of the DataStore Object. Ensure that the key fields defined in the DSO do not include any characteristics that are not allowed for master data.
  Adjust Key Fields: If a characteristic is incorrectly included in the key, remove it from the key definition. You can do this by going to the DSO definition in the SAP BW modeling tools and modifying the key fields.
  Check Characteristic Settings: Verify the settings of the characteristics involved. Ensure that they are correctly defined as master data or transaction data as appropriate.
  Re-activate the DSO: After making changes to the DSO configuration, you may need to re-activate the DSO to apply the changes.
  Test Data Load: After making the necessary adjustments, perform a test data load to ensure that the error is resolved.
