  SAP Error Message:

  Cause:
  This warning message occurs when the value assigned to a particular expression (variable, field, or parameter) is too long and gets truncated (cut) to fit the defined length of the target field or variable. Essentially, the system tries to assign a value that exceeds the length of the receiving field, so it cuts off the excess characters.
  
  Explanation:
  
  The placeholder &1 in the message is replaced by the name of the expression (field or variable) whose value was cut.

  It typically happens during assignments, moves, or when passing parameters where the source string is longer than the target field length.

  If the length is too short to hold the expected data, consider
