• What is the cause and solution for SAP error message NR373 - Field & is not a key field of table & ?

  The SAP error message NR373 ("Field & is not a key field of table &") typically occurs when you are trying to use a field in a context where it is expected to be a key field of a database table, but the specified field is not defined as a key field in that table.
  Cause:
  
  Incorrect Field Usage: You may be trying to use a non-key field in a context that requires a key field, such as in a SELECT statement, JOIN condition, or when defining a primary key in a data structure.
  Table Definition: The field you are referencing is not part of the key fields defined in the table's data dictionary (DDIC).
  Typographical Error: There might be a typo in the field name or table name, leading to the system not recognizing the field correctly.
  
  Solution:
  
  Check Table Definition: Verify the definition of the table in the Data Dictionary (transaction SE11). Ensure that the field you are trying to use is indeed a key field.
  Modify Your Code: If the field is not a key field, you will need to adjust your code to use an appropriate key field instead. This may involve changing your SELECT statements or JOIN conditions.
  Use Correct Field: If you mistakenly referenced a non-key field, replace it with a valid key field from the table.
  Consult Documentation: If you are unsure about the key fields of a table, refer to the SAP documentation or the data dictionary for that specific table.
