• What is the cause and solution for SAP error message NRSCNV026 - Dimension &1 is a line item dimension and is not allowed for remodeling ?

  The SAP error message NRSCNV026 indicates that you are trying to perform a remodeling operation on a line item dimension, which is not permitted in SAP BW (Business Warehouse) or SAP BW/4HANA. Line item dimensions are special types of dimensions that are typically used for detailed transactional data and are not allowed to be remodeled due to their specific characteristics.

  Use Alternative Approaches: If you need to perform analysis that requires different characteristics, consider using other modeling techniques such as:
  
  CompositeProviders: Combine data from multiple sources without changing the underlying dimensions.
  Calculation Views: Use HANA calculation views to create complex data models without altering the original dimensions.
