ABAP MOVE PERCENTAGE Statement syntax and functionality in SAP

MOVE - PERCENTAGE

Short Reference

ABAP Syntax(Obsolete) MOVE source TO destination PERCENTAGE perc [LEFT|RIGHT].

What does it do? This variant of the statement MOVE
(also obsolete), which is not permitted in classes, assigns the subfield of the data object source that begins at the first position and whose length matches the percentage of the total length of source specified in perc , to the data object
destination . By default, and if LEFT is specified,
destination is left-aligned; if RIGHT is specified, it is right-aligned.
The data type of the data objects source and destination
must be character-like, otherwise the addition PERCENTAGE is ignored. perc expects a data object of type i . If the value of perc is less than or equal to 0, nothing is assigned. If the value of perc is greater than or equal to 100, the entire content of source is assigned.
Latest notes: This variant of the statement MOVE can (if required) be replaced by substring accesses with dynamic offsets/lengths or by substring functions
.

Bad example
MOVE c1 TO c2 PERCENTAGE n.

Good example
DATA l TYPE i.

DESCRIBE FIELD c1 LENGTH l.
l = l * n / 100.
MOVE c1(l) TO c2.
