• What is the cause and solution for SAP error message RSDMD030 - Only basic characteristics are allowed for transformation targets ?

  The SAP error message RSDMD030, which states "Only basic characteristics are allowed for transformation targets," typically occurs in the context of data transformation processes in SAP BW (Business Warehouse) when you are trying to create or modify a transformation that involves non-basic characteristics as targets.
  Cause:
  This error arises when you attempt to use non-basic characteristics (like key figures or calculated characteristics) as targets in a transformation. In SAP BW, transformations are designed to map data from a source to a target, and the target must consist of basic characteristics (those that can be directly mapped to InfoObjects).
  Solution:
  To resolve this error, you should ensure that the transformation target consists only of basic characteristics. Here are the steps you can take:
  
  
  Check Transformation Definition: Open the transformation in the SAP BW system and review the target fields. Ensure that all target fields are basic characteristics.
  
  
  Modify Target Fields: If you have included non-basic characteristics in the target, you will need to remove them and replace them with appropriate basic characteristics.
  
  
  Use Key Figures Appropriately: If you need to include key figures or calculated fields, consider creating a separate transformation or using them in a different context where they are allowed.
  
  
  Review Data Flow: Ensure that the data flow from the source to the target is correctly defined and that the target structure aligns with the requirements of the transformation.
  
  
  Test the Transformation: After making the necessary adjustments, test the transformation to ensure that it works without errors.
  
  
  Related Information:
  
  
  Basic Characteristics: In SAP BW, basic characteristics are InfoObjects that can be used as dimensions in a data model. They typically represent attributes like customer, product, or time.
  
  
  Transformation: A transformation in SAP BW is a set of rules that define how data is transferred from a source (like an InfoSource or DataSource) to a target (like an InfoCube or DataStore Object).
  
  
  InfoObjects: These are the building blocks of the SAP BW data model. They can be classified into different types, including characteristics, key figures, and time characteristics.
  
  
  SAP BW Documentation: For more detailed information, refer to the official SAP BW documentation or help resources, which provide guidelines on creating and managing transformations.
  
  
  By following these steps and understanding the underlying concepts, you should be able to resolve the RSDMD030 error effectively.
