  The SAP error message 88507, which states "Do not specify key field &1 as the field for table &2," typically occurs when there is an attempt to use a key field of a database table in a context where it is not allowed, such as in a non-key field position or in a way that violates the data model's integrity.
  Cause:
  
  Key Field Misuse: The error arises when a key field (a field that uniquely identifies a record in a table) is incorrectly specified in a context where it should not be used, such as in a non-key field of a structure or table.
  Data Model Violation: This can happen during the definition of a table, structure, or view where the key field is not allowed to be used as a regular field.
  Incorrect Table Relationships: If there are relationships defined between tables, and the key field is being referenced incorrectly, this error can occur.
  
  Solution:
  
  Review Table Definitions: Check the definition of the table &2 and ensure that the key field &1 is not being used inappropriately. Key fields should only be defined in the key section of the table.
  Adjust Field Usage: If you are trying to use the key field in a non-key context, consider whether you need to reference it differently or if you need to change your design to avoid this misuse.
  Check Data Dictionary: Use transaction SE11 (Data Dictionary) to review the structure of the tables involved. Ensure that the key fields are correctly defined and used.
  Modify ABAP Code: If this error is occurring in ABAP code, review the code to ensure that key fields are not being used in a way that violates the data model. Adjust the code accordingly.
  Consult Documentation: Refer to SAP documentation or help resources for guidance on proper table and field usage.
