• What is the cause and solution for SAP error message RSAR644 - Meta data for InfoSources loaded using RFC ?

  The SAP error message RSAR644 typically indicates an issue related to the metadata of InfoSources that are loaded using Remote Function Call (RFC). This error can occur in the context of SAP BW (Business Warehouse) when there are inconsistencies or problems with the InfoSource metadata.
  Cause:
  
  Inconsistent Metadata: The metadata for the InfoSource may not be consistent with the underlying data source or may not have been properly loaded.
  RFC Connection Issues: There may be issues with the RFC connection to the source system, which can prevent the metadata from being retrieved correctly.
  Transport Issues: If the InfoSource was transported from one system to another, there may be issues with the transport that affect the metadata.
  Missing or Incorrect InfoObject Definitions: The InfoObjects that are part of the InfoSource may not be defined correctly or may be missing in the target system.
  Authorization Issues: The user may not have the necessary authorizations to access the metadata.
  
  Solution:
  
  Check Metadata Consistency: Use transaction RSA1 to check the InfoSource and ensure that the metadata is consistent. You can also use the "Check" function to validate the InfoSource.
  Re-Load Metadata: If the metadata is inconsistent, you may need to reload it. This can be done by using the "Load Metadata" option in the InfoSource settings.
  Verify RFC Connection: Check the RFC connection settings in transaction SM59 to ensure that the connection to the source system is working correctly. Test the connection to confirm it is active.
  Transport Check: If the InfoSource was transported, ensure that all related objects were transported correctly. You may need to re-transport the InfoSource or related objects.
  Check InfoObject Definitions: Ensure that all InfoObjects used in the InfoSource are defined and active in the target system. You can check this in transaction RSA1 under the InfoObjects section.
  Authorization Check: Ensure that the user has the necessary authorizations to access the InfoSource and its metadata. You may need to consult with your security team to verify this.
