• What is the cause and solution for SAP error message RSAOLTP131 - No DataSources of source system &2 were assigned to InfoSource &1 ?

  The SAP error message RSAOLTP131 indicates that there are no DataSources assigned to the specified InfoSource in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence). This error typically arises when you are trying to load data from a source system into an InfoSource, but the necessary DataSources have not been configured or linked properly.
  Cause:
  
  No DataSources Assigned: The primary cause of this error is that the InfoSource you are trying to use does not have any DataSources assigned to it from the specified source system.
  Incorrect Configuration: There may be a misconfiguration in the InfoSource or the DataSources, leading to the absence of a proper link.
  Source System Issues: The source system may not be correctly set up or may not have the required DataSources available.
  Transport Issues: If the InfoSource or DataSources were transported from another system, there may have been issues during the transport process.
  
  Solution:
  To resolve the RSAOLTP131 error, follow these steps:
  
  
  Check DataSource Assignment:
  
  Go to the SAP BW system and navigate to the InfoSource in question.
  Check if any DataSources are assigned to the InfoSource. You can do this by going to the InfoSource maintenance transaction (e.g., RSA1) and looking under the "DataSources" tab.
  
  
  
  Assign DataSources:
  
  If no DataSources are assigned, you need to assign the appropriate DataSources from the source system to the InfoSource.
  Use transaction RSA1 to navigate to the InfoSource and assign the DataSources. You can do this by selecting the InfoSource and using the "Assign DataSources" option.
  
  
  
  Check Source System Configuration:
  
  Ensure that the source system is correctly configured and that the required DataSources are available and activated.
  You can check this in the source system using transaction RSA6 to see the list of available DataSources.
  
  
  
  Transport Issues:
  
  If the InfoSource or DataSources were transported, check the transport logs for any errors or issues that may have occurred during the transport process.
  If necessary, re-transport the objects or manually recreate them in the target system.
  
  
  
  Testing:
  
  After making the necessary changes, test the data extraction process again to ensure that the error is resolved.
