Can't we use MOVE-CORRESPONDING ITAB TO ITAB in the function?

Hi Masters,

I want to transfer the internal table in the code to the function table using move-corresponding, but this is not allowed.I made many tryings. Where am I making a mistake?

Scenario 1 : 

Scenario 2 :

Thanks

You are using the obsolete TABLES in the function module to declare ET_RESULT, so ET_RESULT alone is considered as being the obsolete header table (error prone).

Instead, use:

MOVE-CORRESPONDING gt_temp TO et_result[].

But prefer using ABAP Objects instead of function module, or prefer using EXPORTING over TABLES.

Thank you @Sandra_Rossi.

Since using the TABLE tab in the function module is an old method, we had to use [ ].
What are the ABAP objects you mentioned as the new method? Inside the function "DATA ITAB TYPE TABLE OF XXX." Are you talking about? Because when I use this method I don't have to use "[ ]".

When you said "...or prefer using EXPORTING over TABLES.", did you mean to mention the EXPORT tab in the function module you wanted to talk about?

If returning the "table result" with the help of a function is an old method, how can we do this in another way? I think it is very useful 🙂

ABAP Objects is the "marketing name" of object-oriented ABAP (classes, interfaces, etc.) Create a class pool and method instead of function module. Yes, you are using TABLES in your function module, don't use it, it's obsolete, it declares an obsolete header line too.
