• What is the cause and solution for SAP error message RSCRM150 - Error when determining the field names for &1 from the OLTP ?

  The SAP error message RSCRM150 typically occurs in the context of SAP BW (Business Warehouse) when there is an issue with the extraction of data from the OLTP (Online Transaction Processing) system. This error indicates that there is a problem with determining the field names for a specific data source or InfoSource.
  Cause:
  
  Data Source Configuration Issues: The data source may not be properly configured in the source system. This can include missing or incorrect field mappings.
  Field Name Changes: If there have been changes to the underlying database structure (e.g., field names or data types) in the OLTP system, the BW system may not be able to recognize the fields.
  Transport Issues: If the data source was transported from one system to another, there may be inconsistencies or missing objects.
  Authorization Issues: The user executing the extraction may not have the necessary authorizations to access the data source or the underlying tables.
  Technical Settings: The technical settings of the data source may not be correctly defined, leading to issues in field determination.
  
  Solution:
  
  Check Data Source Configuration: Verify the configuration of the data source in the OLTP system. Ensure that all fields are correctly defined and mapped.
  Update Field Names: If there have been changes to the database structure, update the data source in BW to reflect these changes. This may involve reactivating the data source or adjusting the field mappings.
  Transport Consistency: If the data source was transported, check for any missing objects or inconsistencies. You may need to re-transport or manually adjust the configuration.
  Authorization Check: Ensure that the user has the necessary authorizations to access the data source. This may involve checking roles and permissions in both the OLTP and BW systems.
  Technical Settings Review: Review the technical settings of the data source in the BW system. Ensure that the extraction method and field mappings are correctly defined.
  Re-activate Data Source: Sometimes, simply reactivating the data source in the BW system can resolve the issue. This can be done in the Data Warehousing Workbench (RSA1).
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like RSA1 (Data Warehousing Workbench) and RSA3 (Data Source Test) to troubleshoot and test the data source.
  SAP Notes: Check for relevant SAP Notes that may address specific issues related to the RSCRM150 error. SAP Notes often provide patches or additional guidance for known issues.
  Logs and Traces: Review the logs and traces in the BW system for more detailed error messages that can provide additional context for the issue.
