• What is the cause and solution for SAP error message RSDL112 - DataSource & of DB system & has no type for the specified data ?

  The SAP error message RSDL112 indicates that a DataSource in the database system does not have a defined type for the specified data. This typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when trying to extract data from a source system.
  Cause:
  
  Missing Data Type Definition: The DataSource may not have a defined data type for one or more fields. This can happen if the DataSource was not properly configured or if there were changes in the underlying database schema that were not reflected in the DataSource.
  Inconsistent Metadata: The metadata in the SAP BW system may be inconsistent with the source system, leading to missing or incorrect definitions.
  DataSource Activation Issues: The DataSource may not have been activated properly after changes were made, leading to missing type definitions.
  Database Changes: If there were changes made to the database structure (like adding or removing fields) without updating the DataSource, it can lead to this error.
  
  Solution:
  
  
  Check DataSource Configuration:
  
  Go to the DataSource in the SAP BW system and check the field definitions. Ensure that all fields have the correct data types defined.
  If necessary, redefine the DataSource to include the correct field types.
  
  
  
  Re-activate the DataSource:
  
  If changes were made to the DataSource, ensure that it is activated. You can do this by navigating to the DataSource in the SAP BW system and selecting the activation option.
  
  
  
  Update Metadata:
  
  If the underlying database schema has changed, you may need to update the metadata in the SAP BW system. This can often be done by using the "Replicate DataSource" option to refresh the DataSource definition.
  
  
  
  Check for Notes and Patches:
  
  Sometimes, SAP releases notes or patches that address specific issues. Check the SAP Support Portal for any relevant notes related to your version of SAP BW or the specific DataSource.
