REPLACE IN TABLE itab
Other versions: 7.31 | 7.40 | 7.54
Syntax
REPLACE [{FIRST OCCURRENCE}|{ALL OCCURRENCES} OF] pattern
IN TABLE itab [table_range] WITH new
[IN {CHARACTER|BYTE} MODE]
[replace_options].
Effect
The internal table itab is scanned row-by-row for the character or byte strings
specified by pattern and replaces any occurrences with the content of the operand new. new is a
character-like expression position.
itab expects a standard table without
secondary table keys.
The rows in the table must be character-like or byte-like, depending on the CHARACTER
or BYTE MODE addition. Byte or character strings that cover multiple table rows are not replaced.
The table_range addition
can be used to restrict the search range in the table. When searching in individual table rows, the
other additions operate in the same way as in the statement
REPLACE pattern IN for elementary character or byte strings, with an extra addition,
REPLACEMENT LINE, returning the row number of an occurrence.
In string processing for row types of fixed length, trailing blanks are respected, whereas with new they are ignored.
Note
Replacements using REPLACE IN TABLE give better performance than running
a LOOP and using
REPLACE to make replacements in individual rows.
System Fields
| sy-subrc | Meaning |
|---|---|
| 0 | The search string was replaced by the content of new and the full result is available in the table row(s). |
| 2 | The search pattern was replaced by the content of new and the result of the replacement was truncated on the right in at least one table row. |
| 4 | The search pattern in pattern was not found in the internal table. |
| 8 | The operands pattern or new do not contain interpretable double-byte characters. |
The values of sy-tabix and sy-fdpos are not changed.
Example
A simple "DM-Euro Conversion".

-
Cause: Illegal offset or row specification in the addition of
FROM ... OFFSET ... TO OFFSET.
Runtime Error:INVALID_TABLE_RANGE
