• What is the cause and solution for SAP error message AD614 - Key length in table & > maximum key length (&) ?

  The SAP error message AD614 indicates that the key length in a specified table exceeds the maximum allowed key length. This typically occurs when you are trying to create or modify a database table or index, and the key length exceeds the limits set by the database system.
  
  Cause:
  
  Key Length Exceeded: The primary cause of this error is that the combined length of the fields defined as keys in the table exceeds the maximum key length allowed by the database. Different databases have different limits on key lengths (e.g., for SAP HANA, the maximum key length is typically 255 bytes).
  Data Type Issues: Using data types that consume more bytes than expected (e.g., using CHAR instead of VARCHAR) can also lead to exceeding the key length.
  Composite Keys: If you are using composite keys (multiple fields as a key), the total length of all key fields combined may exceed the limit.
  
  
  Solution:
