• What is the cause and solution for SAP error message RSDL111 - DataSource & is already assigned with InfoSouce & ?

  The SAP error message RSDL111 indicates that a DataSource is already assigned to an InfoSource, which means that the system is preventing you from assigning the same DataSource to another InfoSource. This is a common issue when working with SAP BW (Business Warehouse) and can occur during the configuration of data extraction.
  Cause:
  The error occurs because:
  
  A DataSource can only be assigned to one InfoSource at a time. If you attempt to assign a DataSource that is already linked to another InfoSource, the system will throw this error.
  This is a safeguard to ensure data integrity and avoid conflicts in data extraction processes.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Existing Assignments:
  
  Go to the DataSource in the SAP BW system and check which InfoSource it is currently assigned to. You can do this by navigating to the DataSource in the Data Warehousing Workbench (transaction code RSA1) and looking at its properties.
  
  
  
  Reassign the DataSource:
  
  If you need to assign the DataSource to a different InfoSource, you will first need to remove the existing assignment. This can be done by:
  
  Navigating to the InfoSource that currently has the DataSource assigned.
  Removing the DataSource from that InfoSource.
  After removing it, you can then assign the DataSource to the new InfoSource.
  
  
  
  
  
  Create a New DataSource:
  
  If the DataSource needs to be used in multiple InfoSources, consider creating a new DataSource that replicates the necessary extraction logic. This way, you can have separate DataSources for different InfoSources.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to DataSource and InfoSource assignments for any specific guidelines or best practices.
