• What is the cause and solution for SAP error message RSO_RES_QMSGS102 - Type of source and target object must be identical: &1 &2 ?

  The SAP error message RSO_RES_QMSGS102 indicates that there is a mismatch between the types of source and target objects in a data transfer or transformation process. This typically occurs in scenarios involving data extraction, transformation, and loading (ETL) processes, such as when working with SAP BW (Business Warehouse) or SAP HANA.
  Cause:
  The error arises when the source object (e.g., InfoProvider, DataSource, or Query) and the target object (e.g., InfoObject, DataStore Object, or InfoCube) are not of the same type. For example, you might be trying to transfer data from a DataSource to an InfoCube, but the DataSource is of a different type than what the InfoCube expects.
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Object Types: Verify the types of both the source and target objects. Ensure that they are compatible. For instance, if you are transferring data from a DataSource, ensure that the target is an appropriate InfoProvider that can accept that type of data.
  
  
  Adjust Data Flow: If the source and target objects are indeed of different types, you may need to adjust your data flow. This could involve:
  
  Changing the target object to match the source object type.
  Modifying the source object to ensure it is compatible with the target.
  
  
  
  Review Transformation Rules: If you are using a transformation to map fields from the source to the target, ensure that the transformation rules are correctly defined and that they align with the data types of the source and target.
  
  
  Check for Updates: Sometimes, the issue may arise from outdated objects or configurations. Ensure that all relevant objects are up to date and that any changes in the data model are reflected in the transformations and data flows.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on the types of objects and their compatibility.
  
  
  Testing: After making adjustments, test the data transfer again to ensure that the error has been resolved.
  
  
  Related Information:
  
  SAP BW/4HANA: If you are using SAP BW/4HANA, ensure that you are familiar with the new data modeling concepts and object types introduced in this version.
  Data Modeling: Understanding the data modeling concepts in SAP BW, including InfoProviders, DataSources, and transformations, is crucial for troubleshooting such errors.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message, as there may be specific fixes or recommendations provided by SAP.
