Copying data from one internal table to another

[former_member195355]

Hiya,

I'm looking through some code that copies all the data from one internal table into another internal table, and saw this:

ITAB1[ ] = ITAB2.

CLEAR ITAB2.

I'm just curious as to how this is working, because I would have expected to see:

ITAB1[ ] = ITAB2[ ].

CLEAR ITAB2[ ].

Is it worth adjusting the first code so that it reads ITAB1[ ] = ITAB2[ ] or is it fine as it is?

Thanks in advance!

Accessing the whole internal table (and not just the header line) using square brackets[ ] is relevant for tables with header-line.

Since they are obsolete, i don't see the point of using [ ] to address the whole table. IMHO, this is redundant and i never use it in my code.

This is what ABAP Keyword Documentation has to say about it -

[ ] can be specified for internal tables without header line, but does not need to be. This is because the name (without [ ]) of an internal table without header line is interpreted as the table body in all operand positions regardless.

Same is the case with CLEAR & REFRESH constructs. I had stopped using REFRESH even before it was marked as obsolete
