... [COMPARING { {comp1 comp2 ...}|{ALL FIELDS}|{NO FIELDS} }]
[TRANSPORTING { {comp1 comp2 ...}|{ALL FIELDS} }] ... .
The addition COMPARING compares the specified components comp1 comp2 ... (or the subareas or attributes thereof) in a found line before they are transported with the corresponding components of the work area. If ALL FIELDS is specified, all components are compared. If no NO FIELDS is specified, no components are compared. If the content of the compared components is identical, sy-subrc is set to 0. Otherwise it is set to 2. The found line is assigned to the work area independently of the result of the comparison.
If the addition TRANSPORTING is specified, only the specified components comp1 comp2 ... (and their subareas) in the found line are assigned to the corresponding components of the work area (or their subareas). If ALL FIELDS is specified, all the components are assigned.
COMPARING must be specified before TRANSPORTING. The components comp1 comp2 ... are specified according to the rules in the section Specifying Components. This is subject to the restriction that after TRANSPORTING, attributes of classes cannot be addressed using the object component selector, and after COMPARING, this is only possible as of release 6.10.
