Getting communication_failure at RFC Call starting new Task

[Former Member]

Hallo Everybody,

I´ve got an Issue that when trying Use my RFC that I always get Sy-Subrc 2 - Communication Failure....

I have no idea anymore what to do.

I post my Source Code here and hope u can tell me what´s the issue or how to find out.

I have another rfc - almost identic, working.

I´m checking everything since hours, I hope someone has a hint for me.

Thx so much in advance.

Hi

Have you tried to change the DESTINATION?

I don't think there's a destination called parallel_generators in your system, you should use NONE as destination

Thanks for your reply,

I Used NONE and this Group 'parallel_generators' which I created via sm59 and which works fine with the other rfc.

[Former Member]

where is the destination addressed?

[Former Member]

Sorry, I don´t know exactly what you mean by that.

In SM59 I choose the only Serve I´ve got on the development-System in field instance.

And with another RFC this works.

I just made this test I found at a SAP site as well:

Sy-Subrc is 0 by the way...

SO the group looks fine. Should be if it works with the other rfc.

I will check the to RFC against each other one more time, but there is not so much more to se :-S

I've never used a group for parallel process, so perhaps I'm mistake

but in your code you've assigned parallel_generators to a DESTINATION, not GROUP, perhaps you should use the addition DESTINATION IN GROUP?

This i´ve must have build this failure in while looking for the actual failure.

Now in Debug-Mode I found out that the TASKNAME is stucking and not counting up.

So it works once and not anymore afterwords because the taskname was already used.

So thanks to you I found all the failures - and now I can go into the weekend with a gooooooood Feeling. Thanks a Lot!!!

Yes you're right you're not filling the LV_TASKNAME variable, you're concatenating TASK only
