• What is the cause and solution for SAP error message RMSL_WUI399 - The maximum number of displayed columns in "&1" table is &2 ?

  The SAP error message RMSL_WUI399 indicates that the maximum number of columns that can be displayed in a specific table (denoted by "&1") has been exceeded, with "&2" representing the maximum allowable number of columns. This error typically occurs in the context of SAP applications that utilize the Web User Interface (WUI) or similar frameworks where tables are displayed.
  Cause:
  
  Exceeding Column Limit: The primary cause of this error is that the user is trying to display more columns in a table than the system allows. Each SAP system has a predefined limit on the number of columns that can be displayed in a table view.
  Configuration Settings: The limit may be set in the system configuration, and it can vary based on the specific SAP module or application being used.
  
  Solution:
  
  
  Reduce the Number of Columns: The most straightforward solution is to reduce the number of columns being displayed in the table. This can be done by:
  
  Modifying the table view settings to hide unnecessary columns.
  Creating a custom view that includes only the essential columns.
  
  
  
  Check Configuration Settings: If you have access to system configuration, check the settings related to the maximum number of columns allowed in table views. If necessary, consult with your SAP Basis or system administrator to see if the limit can be increased, although this is not always recommended due to performance considerations.
  
  
  Use Filters: Apply filters to limit the data being displayed, which may allow you to work within the column limit while still accessing the necessary information.
  
  
  Consult Documentation: Review SAP documentation or help resources for specific guidance on managing table views and understanding the limitations of your particular SAP environment.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional context on managing table views.
  User Training: Ensure that users are trained on how to effectively use table views, including how to customize their views to avoid exceeding column limits.
  Performance Considerations: Be aware that displaying too many columns can impact performance, so it's generally advisable to limit the number of displayed columns to only those that are necessary for the task at hand.
