UNPACK Short Reference
ABAP_SYNTAX UNPACK source TO destination.
What does it do? This statement converts the content of the data object source in accordance with special rules and assigns the converted content to the data object destination. source expects the data type p of length 16 without decimal places and no operands of data type decfloat16 or decfloat34 can be used. The data type of destination must be character-like and flat. The conversion is performed according to the following rules:
If the data type of source is not of type p with length 16 and without decimal places, the content of source is converted to this data type. Contrary to the rules described in Conversion Rules for Elementary Data Types, any decimal separator in source is completely ignored.
The digits of the interim result are assigned as right-aligned digits to the data object destination and without a plus/minus sign. Any surplus places in destination are padded with zeros on the left. If the length of destination is not sufficient, it is truncated on the left.
Latest notes:
The function of the statement UNPACK is based on the fact that the BCD representation of a place corresponds to the second half byte of code of a digit in most character representations. This conversion is generally known as Unpacking.
The statement PACK used for packing is obsolete and can be replaced by a regular assignment. ABAP_HINT_END
Example ABAP Coding
After the assignments, char1 and char2 contain the values 123,456 and 0000123456. ABEXA 00752 ABAP_EXAMPLE_END
