• What is the cause and solution for SAP error message NRSCNV395 - Changing the time dimension is not allowed for NCUM InfoCubes ?

  The SAP error message NRSCNV395 indicates that there is an attempt to change the time dimension of a Non-Cumulative (NCUM) InfoCube, which is not permitted. Non-Cumulative InfoCubes are designed to handle data that does not accumulate over time, such as inventory levels or stock balances, and they have specific characteristics regarding their time dimensions.
  Cause:
  The error occurs when a user tries to modify the time characteristics of an NCUM InfoCube. This could happen during various operations, such as:
  
  Attempting to change the time dimension in the InfoCube definition.
  Trying to add or modify time-related attributes or key figures that are not compatible with the NCUM structure.
  
  Solution:
  To resolve this error, consider the following steps:
  
  
  Review the InfoCube Definition: Ensure that you are not attempting to change the time dimension of the NCUM InfoCube. If you need to make changes, you may need to create a new InfoCube instead.
  
  
  Check Data Model Requirements: If you need to analyze data over time, consider whether a different type of InfoCube (e.g., a standard cumulative InfoCube) would be more appropriate for your needs.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for guidance on the limitations and characteristics of NCUM InfoCubes.
  
  
  Use Alternative Approaches: If you need to perform time-based analysis, consider using other reporting tools or methods that can handle time dimensions without altering the InfoCube structure.
  
  
  Seek Expert Assistance: If you are unsure about the changes you need to make, consult with an SAP BW expert or your technical team for advice on how to proceed without violating the constraints of NCUM InfoCubes.
