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

SHIFT - deleting

Short Reference

ABAP Syntax ... { {LEFT DELETING LEADING} | {RIGHT DELETING TRAILING} } mask ... .

What does it do? If you use these additions, the SHIFT statement keeps moving the content of dobj by one position to the left or the right until the content of the first or last position in dobj
is displayed in mask .
If the data object dobj is a string, it is shortened when it is moved to the left but not extended when it is moved to the right. This means the content of mask can also be moved to the right from a string.
In character string processing, mask is a character-type expression position . The system takes account of the capitalization and closing blanks entered in mask . If the content of the first or last position in dobj is not displayed in mask , the content of dobj remains unchanged. The system does not move the objects if mask is an empty string.

Example ABAP Coding After it has been moved to the right, text contains the value "_______I know you" and has a length of 15 characters.
DATA text TYPE string VALUE `I know you know`.

SHIFT text RIGHT DELETING TRAILING 'no kw'.
Example ABAP Coding The following example removes first the closing and then the leading blanks from a string. For strings without leading blanks, this sequence can be used to remove closing blanks.
DATA txt TYPE string VALUE `XXXXX `.

SHIFT txt RIGHT DELETING TRAILING ` `.
