• What is the cause and solution for SAP error message FNDEI_VIEW_PROV155 - CDS view with session variable "APPLICATIONUSER" not supported ?

  The error message FNDEI_VIEW_PROV155 in SAP indicates that there is an issue with a Core Data Services (CDS) view that is trying to use a session variable, specifically APPLICATIONUSER, which is not supported in the context of the CDS view.
  Cause:
  The primary cause of this error is that the CDS view is attempting to utilize a session variable that is not allowed in the context of the view. In SAP, session variables are typically used to capture user-specific data, but not all contexts support their use. The APPLICATIONUSER variable is often used to identify the user executing the application, but if the CDS view is not designed to handle session variables, it will throw this error.
  Solution:
  To resolve this error, you can consider the following approaches:
  
  
  Remove the Session Variable: If the use of the APPLICATIONUSER session variable is not essential for your CDS view, you can modify the view to remove it. This may involve changing the logic of the view to not rely on user-specific data.
  
  
  Use Alternative Logic: If you need to filter or process data based on the user, consider using alternative methods such as:
  
  Using a different approach to pass user information, such as parameters or filters that do not rely on session variables.
  Implementing a different design pattern that allows you to achieve the same goal without using session variables.
  
  
  
  Check for Compatibility: Ensure that the version of SAP you are using supports the features you are trying to implement. Sometimes, certain functionalities may be limited based on the version or configuration of your SAP system.
  
  
  Consult Documentation: Review the SAP documentation related to CDS views and session variables. This can provide insights into the limitations and best practices for using session variables in your specific context.
  
  
  Debugging: If you have access to the development environment, you can debug the CDS view to identify where the session variable is being used and assess whether it can be replaced or removed.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide guidance on using session variables in CDS views.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and what solutions they have implemented.
  CDS View Documentation: Familiarize yourself with the official SAP documentation on CDS views, especially regarding session variables and their limitations.
  
  By following these steps, you should be able to address the FNDEI_VIEW_PROV155 error and successfully implement your CDS view without relying on unsupported session variables.
