• What is the cause and solution for SAP error message RSDS108 - Generation of conversion exits and PSA update... ?

  The SAP error message RSDS108 typically relates to issues encountered during the generation of conversion exits and the update of the Persistent Staging Area (PSA) in SAP Data Warehousing or SAP BW (Business Warehouse) environments. This error can occur for various reasons, and understanding the cause and finding a solution involves several steps.
  Cause:
  
  Data Type Mismatch: The data types in the source system may not match the expected data types in the target structure, leading to conversion exit issues.
  Missing or Incorrect Conversion Exits: If the conversion exits required for the data fields are not defined or are incorrectly defined, this can lead to errors during data loading.
  PSA Table Issues: There may be issues with the PSA table itself, such as corruption or incorrect structure.
  Authorization Issues: Lack of proper authorizations for the user executing the data load can also lead to this error.
  System Configuration: Incorrect configuration settings in the DataSource or InfoPackage can lead to issues during data extraction and loading.
  
  Solution:
  
  Check Data Types: Verify that the data types in the source system match those in the target structure. Adjust the DataSource or InfoObject definitions as necessary.
  Review Conversion Exits: Ensure that all required conversion exits are correctly defined and available in the system. You can check this in transaction SE11 (Data Dictionary) or SE37 (Function Modules).
  Check PSA Table: Inspect the PSA table for any inconsistencies or corruption. You can use transaction RSA1 to check the status of the PSA and perform any necessary repairs.
  Authorization Check: Ensure that the user has the necessary authorizations to perform the data load. This includes access to the DataSource, InfoPackage, and any related objects.
  Reconfigure DataSource/InfoPackage: If there are configuration issues, consider reconfiguring the DataSource or InfoPackage. This may involve adjusting the extraction settings or re-creating the InfoPackage.
  Check Logs: Review the logs for more detailed error messages. You can find logs in transaction SLG1 (Application Log) or in the Data Warehousing Workbench (RSA1).
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as RSA1 (Data Warehousing Workbench), SE11 (Data Dictionary), SE37 (Function Modules), and SLG1 (Application Log).
