[BAPI] Using table as parameter

Former Member — Mon, 09 Jun 2008 14:58:31 GMT

Hey,

trying to use a table type as parameter for an own BAPI. As I try to publish

the BAPI (swo1) I got following error:

"Data type ZBAPI_FPOC_REQUEST cannot be used for methods"

Helps says only data elements and struktures are allowed as reference type.

I'm using a table reference type in my function module. Is this not possible?

What do I have to do if I would like to allow a structure 1..n times in a BAPI?

thx

chris

You will need to use a TABLES parameter against your BAPI and just use the line structure of your table type...

So I am able to include a structure like this in function moduel, but not in bapi?

|-import (structure)

...|- layer1 (structure)

......|- data element

......|- table element

...|-data element

So I have to transform it for BAPI this way????

|-import (structure)

|..|- layer1 (structure)

|.....|- data element

|..|-data element

|- table element (table)

Why does it work in function module with first structure in not in BAPI?

So everytime I have to insert input in BAPI with occurency 1..n I have to

insert a table??

How many tables with different structure I'm able to insert?

thanks

chris

Hi,

There is absolutely no difference technically between a BAPI and a function module - a BAPI is just a specific type of function module so there shouldn't be any problem from that perspective.

You can use DDIC table types as import and export parameters or you can use a DDIC structure to define a table against your function module interface. You can insert lots of tables - just go to the tables tab and add them as you need with their type set to a DDIC structure.

Are you trying to call the function module from an external system as an RFC?

I seem to recall that table types as import/export parameters don't work for certain external calls, say via JCo or Web Dynpro models or something (I really can't remember at the moment) - just wondering if that is why you are seeing the error?

hi,

the function module I called from se37 and even with table types in structure I can

call it without a problem. If I try to publish this function module in BOR he returns

an error.

Now I transformed my function module, so that every table I have to use is in

tab table and no table type in a structure, but I didn't try it yet to publish in BOR.

Hi Chris,

I definitely think it is because you are trying to publish it for external systems. As you have found, there is no problem using table types in function modules.
