• What is the cause and solution for SAP error message GH060 - No foreign key can be created for field & ?

  The SAP error message GH060, which states "No foreign key can be created for field &," typically occurs when you are trying to create a foreign key relationship in the Data Dictionary (SE11) or during the definition of a table or structure, but the system detects that the conditions for creating a foreign key are not met.
  Causes:
  
  Data Type Mismatch: The field you are trying to link as a foreign key does not have a compatible data type with the primary key of the referenced table.
  Field Length Mismatch: The length of the foreign key field does not match the length of the primary key field in the referenced table.
  Domain Mismatch: The domains of the fields do not match, meaning they may have different value ranges or data types.
  Field Attributes: The attributes of the fields (like whether they are nullable or not) may not be compatible.
  Table Status: The table or structure you are trying to modify may be in a status that does not allow changes (e.g., it is active or locked).
  Non-Unique Key: The field you are trying to reference may not be a unique key in the referenced table.
  
  Solutions:
  
  Check Data Types: Ensure that both the foreign key and the primary key fields have the same data type (e.g., CHAR, INT, etc.).
  Check Field Lengths: Make sure that the lengths of the fields match. If the primary key is 10 characters long, the foreign key should also be 10 characters long.
  Verify Domains: Check the domains of both fields to ensure they are compatible. If they are different, consider changing the domain of the foreign key field.
  Review Field Attributes: Ensure that the attributes of both fields are compatible, especially regarding nullability.
  Check Table Status: If the table is active, you may need to deactivate it or create a new version to make changes.
  Ensure Unique Key: Make sure that the field you are trying to reference in the foreign key relationship is a unique key in the referenced table.
