• What is the cause and solution for SAP error message RSDD_TIP_LOGI122 - Key not allowed (loading behaviour of facts is insert-only) ?

  The SAP error message RSDD_TIP_LOGI122 indicates that there is an issue related to the loading behavior of facts in a data model, specifically that the loading behavior is set to "insert-only." This means that the system is configured to only allow new records to be inserted into the fact table, and it does not permit updates or deletions of existing records.
  Cause:
  The error typically occurs in the following scenarios:
  
  Insert-Only Configuration: The InfoObject or the fact table is configured to allow only insert operations. This is common in scenarios where historical data is preserved, and changes to existing records are not allowed.
  Data Load Attempt: An attempt is made to load data that conflicts with the insert-only behavior, such as trying to update or delete existing records.
  Key Violations: The data being loaded may contain keys that already exist in the fact table, which violates the insert-only constraint.
  
  Solution:
  To resolve this error, consider the following approaches:
  
  
  Check Loading Behavior:
  
  Review the loading behavior of the InfoObject or the fact table. If updates or deletions are necessary, you may need to change the loading behavior from "insert-only" to allow updates or deletions.
  
  
  
  Data Preparation:
  
  Ensure that the data being loaded does not contain keys that already exist in the target fact table. You may need to filter out or modify the incoming data to avoid key conflicts.
  
  
  
  Use of Delta Loads:
  
  If applicable, consider using delta loads instead of full loads. Delta loads can help manage changes more effectively without violating the insert-only constraint.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or consult with your SAP Basis or BW team to understand the implications of changing the loading behavior and to ensure that it aligns with your data management strategy.
  
  
  
  Error Logs:
  
  Check the error logs for more detailed information about the specific records causing the issue. This can help identify the exact nature of the conflict.
