MODIFY itab - itab_line

Short Reference

Syntax

... { table_key  | index } FROM wa
                          [TRANSPORTING comp1 comp2 ...]
                          [result].

Addition:

... TRANSPORTING comp1 comp2 ...

Effect

In this variant, the statement MODIFY assigns the content of work area wa to a row specified by a table key in table_key or by a row number in index. wa is a general expression position.

Use TRANSPORTING to restrict the components comp to be modified. Use result when changing a single row to set a reference to the changed row in the form of a field symbol or a data reference.

For access using table keys, index access to sorted tables and when the TRANSPORTING addition is used, the wa work area must be compatible with the line type of the primary internal table. Only in the case of insertion using the table index in standard tables without the TRANSPORTING addition can wa be incompatible with the line type of the internal table, and is converted to the line type according to the conversion rules. If an arithmetic expression is specified for wa, the row type of the internal table is considered when determining the calculation type ein.

Notes

Addition

... TRANSPORTING comp1 comp2 ...

Effect

The TRANSPORTING addition has the effect that only the declared comp1 comp2 ... components of the work area are assigned to the corresponding components of the line(s) to be changed. For sorted tables and hashed tables, no primary table key components may be declared after TRANSPORTING.

The comp1 comp2 ... component specifications are made in accordance with the rules specified in Component declaration, with the constraint that after TRANSPORTING, no attributes of classes can be addressed using the object component selector.
