• What is the cause and solution for SAP error message RSAU208 - No source InfoObject assigned to InfoObject & (data field: &) ?

  The SAP error message RSAU208 indicates that there is no source InfoObject assigned to the specified InfoObject in the context of data extraction or transformation processes, particularly in SAP BW (Business Warehouse) or SAP BI (Business Intelligence). This error typically arises when you are trying to load data into an InfoObject that does not have a corresponding source defined.
  Cause:
  
  Missing Assignment: The InfoObject in question does not have a source InfoObject assigned to it. This can happen if the InfoObject was created but not properly configured.
  Incorrect Data Flow: The data flow or transformation process may not be correctly set up, leading to the absence of a source InfoObject.
  Changes in Data Model: If there have been recent changes to the data model, such as deletions or modifications of InfoObjects, it may lead to this error.
  Transport Issues: If the InfoObject was transported from one system to another, it may not have been fully configured in the target system.
  
  Solution:
  
  
  Check InfoObject Configuration:
  
  Go to the InfoObject maintenance transaction (e.g., RSA1) and check the configuration of the InfoObject that is causing the error.
  Ensure that a source InfoObject is assigned to it.
  
  
  
  Assign Source InfoObject:
  
  If the source InfoObject is missing, you need to assign it. This can be done in the InfoObject maintenance screen by navigating to the relevant settings and linking the appropriate source InfoObject.
  
  
  
  Review Data Flow:
  
  Check the data flow and transformation settings in the Data Warehousing Workbench (RSA1). Ensure that the transformation rules are correctly defined and that the source and target InfoObjects are properly linked.
  
  
  
  Check for Changes:
  
  If there have been recent changes to the data model, review those changes to ensure that they did not inadvertently remove or alter the source InfoObject assignments.
  
  
  
  Transport Validation:
  
  If the InfoObject was transported, validate that all necessary components and configurations were included in the transport request.
  
  
  
  Re-activate InfoObjects:
  
  Sometimes, re-activating the InfoObject can resolve issues. You can do this by going to the InfoObject maintenance and re-activating it.
