• What is the cause and solution for SAP error message RSDODSO258 - Number of key fields (&1) exceeds limit (&2) ?

  The SAP error message RSDODSO258 indicates that the number of key fields defined for a DataStore Object (DSO) exceeds the allowed limit. This error typically occurs when you are trying to create or modify a DSO and the number of key fields you are trying to define surpasses the maximum limit set by the system.
  Cause:
  
  Exceeding Key Field Limit: The primary cause of this error is that the number of key fields you are trying to define for the DSO exceeds the maximum allowed limit. In SAP BW, the limit for key fields in a DSO is typically 16.
  Incorrect Configuration: It may also occur due to incorrect configuration or misunderstanding of the data model requirements.
  
  Solution:
  
  Review Key Fields: Check the number of key fields you have defined for the DSO. If it exceeds the limit, you will need to reduce the number of key fields.
  Reassess Data Model: Reassess your data model to determine if all the key fields are necessary. Consider whether some fields can be combined or if certain fields can be removed from the key.
  Modify DSO Definition: If you are in the process of creating or modifying the DSO, go back to the definition and adjust the key fields accordingly.
  Consult Documentation: Refer to SAP documentation or guidelines for best practices on defining key fields in DSOs.
  
  Related Information:
  
  Key Fields in DSO: Key fields are essential for uniquely identifying records in a DSO. They play a crucial role in data retrieval and integrity.
  SAP BW/4HANA: If you are using SAP BW/4HANA, the limits and configurations may differ slightly, so always refer to the specific version documentation.
  Performance Considerations: Having too many key fields can also impact performance, so it's essential to keep the number of key fields to a minimum while still meeting business requirements.
