ID PACK • PACK ABAP Statement • TO PACK (obsolete)
PACK Short Reference
ABAP_SYNTAX_OBS PACK source TO destination.
What does it do? This statement, which is forbidden in classes, converts the content of the data object source to the data type p of length 16 without decimal places. In contrast to the conversion rules for elementary data types, any decimal separators in source are ignored. This assigns the converted content to the data object destination. The data type of source must be character-like, flat, and its content must be interpretable as a numeric value. The data type of destination must be flat. If destination has the data type p, the intermediate result is assigned to it from right to left. Surplus places are cut off on the left, and the decimal places are determined by the data type of destination. If destination does not have the data type p, the intermediate result is converted to the data type of destination in accordance with the rules in the conversion table for source field type p .
Latest notes:
The function of the statement PACK is based on the fact that the second half-byte of the code of a digit in most character representations matches the BCD representation of the associated numeric value. This conversion is generally known as packing.
If the source field contains a number without a decimal separator, and the target field has dobj2 of data type p with sufficient length and without decimal places, the result of the PACK statement matches the result of a regular statement.
The statement UNPACK does not demonstrate the same behavior as a regular assignment and is therefore not yet obsolete. ABAP_HINT_END

Runtime Exceptions
Catchable Exceptions CX_SY_CONVERSION_NO_NUMBER
Reason for error:
Source field cannot be interpreted as a number
Runtime error:
CONVT_NO_NUMBER CX_SY_CONVERSION_OVERFLOW
Reason for error:
Overflow during conversion (type p)
Runtime error:
BCD_OVERFLOW
Non-catchable Exceptions
Reason for error:
Source field (type p) contains an incorrect BCD format
