• What is the cause and solution for SAP error message RSTRAN508 - Key rule (target field: &2): Initial update selected ?

  The SAP error message RSTRAN508 indicates that there is an issue with the data transfer process in SAP BW (Business Warehouse) related to the key figure or target field specified in the message. The message typically means that an initial update has been selected for a key figure that does not allow it, or that the data being processed does not meet the requirements for an initial load.
  Cause:
  
  Initial Update Selection: The error occurs when an initial update is selected for a key figure that is not configured to accept initial updates. This can happen if the data source or the target InfoObject is not set up correctly.

  Solution:
  
  Check DTP Settings: Review the Data Transfer Process (DTP) settings for the data source and ensure that it is configured to allow initial loads. You may need to adjust the settings to enable initial updates.
  Review Target InfoObject: Check the configuration of the target InfoObject (the key figure or field specified in the error message). Ensure that it is set up to accept initial updates.
  Data Source Configuration: Verify the configuration of the data source to ensure it is compatible with initial loads. If necessary, adjust the settings to allow for initial updates.
  Re-run the Process: After making the necessary adjustments, re-run the data transfer process to see if the error persists.
