• What is the cause and solution for SAP error message RSAR255 - You are not allowed to maintain InfoSources of ERP systems manually ?

  The SAP error message RSAR255, which states "You are not allowed to maintain InfoSources of ERP systems manually," typically occurs in the context of SAP BW (Business Warehouse) when a user attempts to manually maintain or modify InfoSources that are linked to ERP systems. This restriction is in place to ensure data integrity and consistency, as InfoSources are critical components in the data extraction process from ERP systems.
  Cause:
  The primary cause of this error is related to authorization issues. Specifically, the user attempting to maintain the InfoSource does not have the necessary permissions to perform this action. SAP has built-in security measures to prevent unauthorized changes to critical data structures, especially those that are linked to ERP systems.
  Solution:
  To resolve this issue, you can take the following steps:
  
  
  Check User Authorizations:
  
  Ensure that the user has the appropriate authorizations to maintain InfoSources. This typically involves checking the user's roles and profiles in the SAP system.
  The relevant authorization object is S_BW_AUTH, which controls access to BW objects. Ensure that the user has the necessary authorizations for InfoSources.
  
  
  
  Role Assignment:
  
  If the user lacks the necessary authorizations, you may need to assign them a role that includes the required permissions. This can be done by a system administrator or someone with the appropriate access rights.
  
  
  
  Use Transaction Codes:
  
  If you are an administrator, you can use transaction codes like PFCG to manage roles and authorizations. You can also check the specific InfoSource settings using transaction RSA1 (Data Warehousing Workbench).
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to InfoSources and authorizations for any additional context or specific configurations that may be required.
  
  
  
  Contact SAP Support:
  
  If the issue persists after checking authorizations, consider reaching out to SAP support for further assistance. They may provide insights based on the specific version of SAP you are using.
