• What is the cause and solution for SAP error message DT296 - &-&: Too long for use as key field (>=&) ?

  The SAP error message DT296 indicates that a field you are trying to use as a key field is too long. Specifically, the message states that the length of the field exceeds the maximum allowed length for key fields in the context you are working with.
  Cause:
  
  Field Length Exceeded: The field you are trying to use as a key has a length that is greater than what is allowed for key fields in the database table or structure.
