RSDMD029 - Details

• The SAP error message RSDMD029, which states "Only basic characteristics are allowed for transformation sources," 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.
  
  Cause:
  This error arises when you attempt to use a non-basic characteristic (like a hierarchy, attribute, or a characteristic that is not a key figure) as a source in a transformation. In SAP BW, transformations are designed to map data from a source (like an InfoSource or DSO) to a target (like a Data Target or InfoCube), and only basic characteristics (those that are key fields) can be used as sources in this context.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Transformation Definition:
  
  Open the transformation that is causing the error.
  Review the source fields you have selected. Ensure that all source fields are basic characteristics.
  
  
  
  Modify the Source
