Performance difference between MOVE and = assignment in ABAP

Question

Is there any kind of performance gain between 'MOVE TO' vs x = y? I have a really old program I am optimizing and would like to know if it's worth it to pull out all the MOVE TO. Any other general tips on ABAP optimization would be great as well.

Answer 1

No, that is just the same operation expressed in two different ways. Nothing to gain there. If you're out for generic hints, there's a good book available that I'd recommend studying in detail. If you have to optimize a specific program, use the tracing tools (transaction SAT in sufficiently current releases).

Answer 2

The two statements are equivalent:

" To assign the value of a data object source to a variable destination, use the following statement:

MOVE source TO destination.

or the equivalent statement

destination = source.
