• What is the cause and solution for SAP error message DT482 - Key & is too wide; table will not be created on DB & ?

  The SAP error message DT482 indicates that a key field in a database table is too wide, which prevents the table from being created in the database. This typically occurs when the combined length of the key fields exceeds the maximum allowed size for a primary key in the underlying database system.
  
  Cause:
  
  Key Field Length: The total length of the key fields defined in the table exceeds the maximum limit set by the database. Different databases have different limits for key lengths (e.g., in some databases, the maximum length for a primary key can be 900 bytes).
  Data Types: The data types of the key fields may have large sizes (e.g., VARCHAR, CHAR) that contribute to the overall length.
  Multiple Key Fields: If there are multiple fields defined as part of the primary key, their combined length may exceed the limit.
  
  
  Solution:
  
  Review Key Fields: Check the definition of the key fields in the table.
