• What is the cause and solution for SAP error message RSDMD029 - Only basic characteristics are allowed for transformation sources ?

  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 Fields:
  
  If you have included non-basic characteristics, remove them from the transformation source.
  Replace them with appropriate basic characteristics that are allowed.
  
  
  
  Use Attributes or Hierarchies Appropriately:
  
  If you need to use attributes or hierarchies, consider creating a separate transformation or process that handles these elements appropriately.
  
  
  
  Validate the Data Model:
  
  Ensure that the data model is correctly set up, and that the characteristics you are using are defined as basic characteristics in the InfoObject settings.
  
  
  
  Check for Updates:
  
  If you are using an older version of SAP BW, consider checking for updates or patches that might address this issue.
  
  
  
  Related Information:
  
  Basic Characteristics: These are characteristics that can be used as key fields in data modeling. They are typically used for filtering and aggregating data.
  Transformation: A transformation in SAP BW is a set of rules that define how data is transferred from a source to a target.
  InfoObjects: These are the building blocks of the SAP BW data model, which can be characteristics, key figures, or other data types.
  
  If you continue to experience issues after following these steps, it may be helpful to consult SAP documentation or reach out to SAP support for further assistance.
