export parameters in a Z function module

[former_member189629]

Hi All,

I have a program that returns data in an internal table. While converting the program J_into a custom FM, <b>is it a must that the exporting table (with data) be declared with reference to a dictionary table/structure?</b>

When using EXPORTING paramater with a table, I think it must be defined using a Table Type, when using a TABLES parameter, it can be like a structure, but it also doesn't have to have a type.

I was hoping you should answer this query Rich

You mean the table being exported from the FM has to have a dictionary reference right?

[former_member189629]

I mean the exporting table (say E_MARA) should be referred to a dictionary type (E_MARA TYPE MARA)?

Can't a normal itab declaration in the FM do?

[RichHeilman]

I believe that it does, and it must be a table type.

You must use a table type defined in the data dictionary.

Thank you, Sir.

You can export data in a table parameter with generic Type reference TABLE (any data).

[RichHeilman]

Right, you can gernerically define in TABLES parameter, but in EXPORT parameter, you need to use a table type from ABAP dictionary.

I just created, checked & activated a Ztable in the DDIC but it is not being recognized by the FM. Says it doesn't exist. What could be the prob?

[RichHeilman]

Did you create a "Z" transparent table or a table type? You need to create a table type in SE11, select radiobutton for Data Element(Data Type).

Hi

It depend on where you're using that ZTABLE and what's the ZTABLE:

- As reference for an export/import parameter?

- As reference for a TABLE parameter?

Rich

Riccardo is right, I don't know which release you're using (my rel. is 4.6C), but It's possible to use the generic type TABLE to define an import or export parameter as table.

Then I stand correctly, I assumed that you could only use Tables Types when defining a table in an exporting parameter.

Hi Max,

I have an internal table being populated exported from the FM. So my question was whether reference for an export/import parameter should be to the DDIC.

BTW I am on ECC 5.0

Hi

No you don't need to do that, but it would be better to do because it wouldn't be easy to manage a table without reference, you should use the field-symbols.

So I believe it's better to define a dictionary structure like your internal table and define a TABLE paramenter like that structure.
