• What is the cause and solution for SAP error message WK201 - You have reached the maximum number of columns which can be selected ?

  SAP Error Message:
  
  WK201 - You have reached the maximum number of columns which can be selected
  
  Cause:
  This error occurs when you try to select more columns than the system allows in a particular SAP workflow or report selection screen. SAP has a predefined limit on the number of columns that can be displayed or selected in certain list or table controls (such as ALV grids or workflow selection screens). When this limit is exceeded, the system throws the WK201 error.
  
  Where it typically occurs:
  
  In SAP Workflow (e.g., when selecting columns in the workflow inbox or task lists)
  In ALV (ABAP List Viewer) reports or selection screens with column selection options
  In custom reports or transactions where dynamic column selection is implemented
  
  
  Solution:
  
  
  Reduce the number of selected columns:
  
  Limit the number of columns you select to be within the allowed maximum. Usually, this means deselecting some columns or choosing only the essential ones.
  
  
  Check system limits:
  
  The maximum number of columns is often controlled by SAP standard settings or program logic. If you are a developer or have access to customization:
  
  Review the program or screen logic to understand the limit.
  Adjust the program logic if possible (e.g., increase the limit if technically feasible and performance allows).
  
  
  
  Use alternative display options:
  
  If you need to see more data, consider:
  
  Exporting data to Excel for further analysis.
  Using multiple reports or views with fewer columns each.
  Implementing a custom report with pagination or dynamic column loading.
  
  
  
  SAP Notes and Support:
  
  Check SAP Notes for any known issues or patches related to this error message. Sometimes SAP releases notes that increase limits or provide workarounds.
  
  
  
  Related Information:
  
  The maximum number of columns is often limited to ensure performance and usability.
  In ALV Grid Control, the limit can be related to the maximum number of fields that can be displayed or selected.
  In SAP Workflow, the selection screen for columns might have a hardcoded limit.
  If you are a developer, you can check the relevant function modules or classes handling the column selection to see if the limit can be adjusted.
