• What is the cause and solution for SAP error message RSDD_LM156 - Parent &1 of navigational attribute &2 in column &3 is not selected ?

  The SAP error message RSDD_LM156 indicates that there is an issue with the selection of a parent node for a navigational attribute in a query. This error typically occurs in the context of SAP BW (Business Warehouse) when working with queries in BEx (Business Explorer) or when using navigational attributes in InfoProviders.
  Cause:
  The error message "Parent &1 of navigational attribute &2 in column &3 is not selected" suggests that:
  
  A navigational attribute (e.g., a characteristic that provides additional context to a key figure) is being used in a query.
  The parent of this navigational attribute is not included in the query selection.
  This can happen if the navigational attribute is dependent on a parent characteristic that is not selected in the query, leading to inconsistencies in the data retrieval.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Query Design:
  
  Open the query in the BEx Query Designer.
  Verify that the parent characteristic of the navigational attribute is included in the query. If it is not, add it to the query.
  
  
  
  Modify the Query:
  
  If the parent characteristic is not needed for your analysis, consider removing the navigational attribute from the query.
  Alternatively, if the parent characteristic is essential, ensure it is selected in the query layout.
  
  
  
  Validate Hierarchies:
  
  If the navigational attribute is part of a hierarchy, ensure that the hierarchy is correctly defined and that the parent-child relationships are intact.
  
  
  
  Check Data Model:
  
  Review the data model in the InfoProvider to ensure that the navigational attributes and their parent characteristics are correctly defined and linked.
  
  
  
  Test the Query:
  
  After making the necessary adjustments, execute the query again to see if the error persists.
