  SAP Error Message:
  WER064 - Item field &1 (&2) is not defined for application &3
  
  Meaning / Cause:
  This error occurs when a particular item field (data element or field name) is referenced or used in a context (application) where it is not defined or allowed. In other words, the system expects certain fields to be defined for a specific application area, and the field you are trying to use is not part of that definition.
  
  &1 = Field name (technical name of the item field)
  &2 = Field description or additional identifier
  &3 = Application area (e.g., SD, MM, FI, etc.)
  
  This typically happens in scenarios involving:
  
  Customizing or configuration of document item fields.
  Enhancements or user exits where fields are added or referenced incorrectly.
  Using fields in output determination, pricing, or other application-specific processes where the field is not recognized.
  
  
  Common Scenarios:
  
  You try to add or use a field in a sales document item that is not defined in the sales application.
  During output determination or condition technique, a field is referenced that is not valid for the application.
  In ALE/IDoc processing, a field is used that is not part of the message type or application segment.
  Custom developments or enhancements incorrectly reference fields.
  
  
  Solution / How to Fix:
  
  
  Check Field Definition:
  
  Verify if the field (&1) is defined for the application (&3) in the relevant customizing or data dictionary.
  Use transaction SE11 to check the data element and table structure.
  Check if the field is part of the application-specific structure or segment.
  
  
  
  Adjust Configuration:
  
  If you are configuring output determination, pricing, or similar, ensure that the field is allowed for the application.
  Use transaction SPRO to navigate to the relevant customizing and verify field assignments.
  
  
  
  Correct Enhancements or User Exits:
  
  Review any custom code or user exits/enhancements where the field is referenced.
  Make sure the field is valid for the application context.
  If necessary, add the field properly via append structures or enhancement spots.
  
  
  
  Check Application-Specific Tables:
  
  Some applications have specific tables or structures defining allowed fields.
  For example, in SD, check tables like TVARV, TVARVC, or application-specific customizing tables.
