• What is the cause and solution for SAP error message RSDODSO151 - DataStore object &1: Navigation attribute &2 is added again ?

  The SAP error message RSDODSO151 indicates that there is an issue with a DataStore Object (DSO) where a navigation attribute is being added again, which is not allowed. This typically occurs when you attempt to add a navigation attribute to a DSO that has already been defined as a navigation attribute.
  Cause:
  
  Duplicate Definition: The navigation attribute you are trying to add is already defined in the DataStore Object.
  Modeling Error: There may be a misunderstanding in the modeling of the DSO, where the same attribute is being mistakenly added again.
  Transport Issues: If changes were transported from one system to another, there might be inconsistencies in the DSO definitions.
  
  Solution:
  
  Check Existing Attributes: Review the existing attributes of the DataStore Object to confirm if the navigation attribute is already defined. You can do this by navigating to the DSO in the Data Warehousing Workbench (transaction RSA1).
  Remove Duplicate Definition: If the navigation attribute is already present, you do not need to add it again. Remove the attempt to add the duplicate navigation attribute.
  Adjust Modeling: If you intended to add a different attribute, ensure that you are selecting the correct one and that it is not already defined as a navigation attribute.
  Transport Consistency: If this issue arose after a transport, ensure that the transport was successful and that the DSO definitions are consistent across systems.
