ABAP MODIFY ITAB Statement syntax, information and example SAP source code

MODIFY itab

Short Reference

ABAP Syntax MODIFY { itab_line
| itab_lines }.

What does it do? This statement changes the content of one or more rows itab_line or itab_lines , specified using a table key or a table index.
The following limitations apply when modifying key fields of the primary and secondary table key s:
The administration of unique secondary keys is updated directly after a modification using MODIFY , and produces an unhandleable exception if duplicate entries were to result. The non-unique secondary keys are updated when the secondary table key is next used explicitly (
lazy update ).

System Fields
sy-subrc Meaning
0At least one row was changed.
4No rows were changed, since no suitable row was found during the search using a table key or in the logical expression, or the specified index was greater than the current number of rows for the search using a table index.
The system field sy-tabix is not set.

Latest notes: Apart from using the MODIFY statement, the content of an individual table row can be changed using assignments to field symbols and dereferenced data references that point to the table row.
