ABAP SHIFT PLACES Statement syntax, information and example SAP source code

SHIFT - places

Short Reference

ABAP Syntax ... {BY num PLACES} | {UP TO substring} ... .

ABAP_VARIANTS:
1 ... BY num PLACES ... .
2 ... UP TO substring ... .

ABAP_VARIANT_1 ... BY num PLACES ... .

What does it do? The content of dobj is shifted to the left or right (as specified by direction ) by the positions specified in num . num is a numerical expression position
of operand type i . If the content of num is less than or equal to 0, the content of the data object dobj remains unchanged.

Example ABAP Coding Using the statement FIND , the offset of the word "you" in text is determined and its content is shifted by this length to the left or right. After the shift, text contains "you know" and is eight characters long.
DATA: text TYPE string VALUE `I know you know`,
off TYPE i.

FIND 'you' IN text MATCH OFFSET off.

SHIFT text BY off PLACES.

ABAP_VARIANT_2 ... UP TO substring ... .

What does it do? In the data object dobj , the first substring is searched for whose contents match those of substring . This is case-sensitive. The content of the data object dobj will be shifted as far possible left or right (as specified in direction ) until the byte or character string contained in substring is at the position that is at the beginning or end of the data object dobj before the shift.
substring expects a character-like or byte-like data object. If
substring is an empty string, the position in front of the first character or byte is found. To the left, no shift will take place, and to the right there will be a shift by the entire length of dobj .
In character string processing, substring is a character-like expression position ; in data objects, substring with a fixed length respects the trailing blanks.

System fields
sy-subrc Meaning
0The substring in substring was found in the data object
dobj and its contents were moved accordingly.
4The substring in substring was not found in the data object dobj and its contents remain unchanged.

Latest notes: If you have data objects of fixed length, the substring searched for after the shift is either (depending on the direction) flush left at the beginning or flush right at the end of the data object. If you have strings, the data object is lengthened to the right through the shift. Therefore, the substring is not at the right margin after the shift.

Example ABAP Coding This example has the same result as the previous example. However, here the search for "you" is not performed in the statement SHIFT itself.
DATA text TYPE string VALUE `I know you know `.

SHIFT text UP TO 'you'.
