  SAP Error Message:
  
  WRF_APC528 – Select a language to perform the desired action
  
  Cause:
  This error occurs when a user tries to perform an action in SAP (often related to SAP Workflow, APC - Advanced Planning and Optimization, or other modules involving language-dependent data) without having selected a language. The system requires a language context to proceed because certain data or actions are language-specific.
  Common scenarios include:
  
  Attempting to display or edit texts, descriptions, or messages that are language-dependent.
  Working with master data or customizing entries that require a language selection.
  Running reports or transactions that need a language parameter but none was provided.
  
  
  Solution:
  To resolve the error WRF_APC528, you need to explicitly select or specify a language before performing the action. Here are the steps:
  
  
  Select Language in the Screen:
  
  Look for a language dropdown or input field on the screen where the error occurs.
  Choose the appropriate language (e.g., EN for English, DE for German) and confirm.
  
  
  
  Set Default Logon Language:
  
  If the language selection is missing or not prompted, check your user logon language.
  You can set or change your default logon language in SAP GUI under:
  
  System ? User Profile ? Own Data ? Defaults tab ? Logon Language
  
  
  Set it to the desired language and save.
  
  
  
  Check Transaction or Program Parameters:
  
  Some transactions or reports require a language parameter.
  Make sure to enter the language code when prompted or in the selection screen.
  
  
  
  Verify Language Settings in Customizing:
  
  If the error occurs during customizing or master data maintenance, ensure that the language-dependent texts or entries exist for the selected language.
  If not, create or maintain the required language entries.
  
  
  
  Technical Note:
  
  If this error appears in a custom program or workflow, ensure that the language parameter is passed correctly in the code or workflow container.
