Flow Logic : Call of a RFC Function Module passing back a table

[Former Member]

Hi forum,

I cerated a service w/ templates including some flow logic files accoringly.

All what I want to achieve for the beginning to call an RFC FM that returns back a table that can be e.g. being shown on the html page (template).

I managed to pass simple fields back and forth. But as soon as I try to pass back a table. It doesn't work regardless, if the table ist definded untder TABELS or passed out under EXPORT parameter.

I always find the ITS Context the following:

borerrormsg = Failed to retreive RFC method `Z_R1W_RS_ITS_TEST_TAB'. Check if method exists or program exception occured

But I reduced the RFC function (which it is not a method), so that there are no exceptions anymore.

Please help - I am missing somehting aubstantial but what !??

Cheers,

Chris

Hi,

I had done the same scenario using flow logic.These are the steps i followed :

Say if we have a table named ZTEST in TABLES for your RFC and ZTEST has fields Name,Telephone etc

Then call the RFC from flow logic as follows :

<module name="ZTEST" type="RFC">

Give input mapping if required

</module>

To retreive the values in HTML use the following code in HTML Template :

`repeat with i from 1 to ZTEST-NAME.dim`

Then use `ZTEST-NAME(i)` to get the name at ith row.

Hope this helps. Do get back for further classification.

Hi Vijth,

thanks for your reply! But this is exactly what I tried but I still encounter the problem. As soon I remove the table from the equation (RFC Module), it works like a champ!

But with the table I get the error as described above!

Any settings are missing !? What could be the problem here !?

Cheers,
