• What is the cause and solution for SAP error message CUSDIR806 - Field &1 is not a key field in table &2 ?

  The SAP error message CUSDIR806 indicates that a specific field (denoted as &1) is not defined as a key field in the specified table (denoted as &2). This error typically arises when you are trying to perform an operation that requires the field to be a key field, such as creating a new entry, updating an existing entry, or performing a lookup.
  Cause:
  
  Field Definition: The field you are trying to use is not part of the primary key or any unique key of the specified table. In SAP, key fields are essential for uniquely identifying records in a table.
  Incorrect Configuration: There may be a configuration issue where the field is expected to be a key field but is not defined as such in the database table.
  Custom Development: If you are working with custom tables or enhancements, the field may not have been properly defined in the data dictionary.
  
  Solution:
  
  
  Check Table Definition: 
  
  Use transaction code SE11 (Data Dictionary) to check the definition of the table (table name &2). Look at the key fields defined for the table and verify if the field (&1) is included.
  
  
  
  Modify Table Structure:
  
  If you have the necessary authorizations and it is appropriate for your business logic, you can modify the table structure to include the field as a key field. This is done using transaction SE11, but be cautious as this can have significant implications on data integrity and application logic.
  
  
  
  Adjust Your Logic:
  
  If modifying the table is not feasible, you may need to adjust your logic to use a different field that is a key field in the table. Review the business requirements to determine if there is an alternative approach.
  
  
  
  Consult Documentation:
  
  Review any relevant documentation or specifications related to the table and its fields to ensure you are using the correct fields for your operations.
