Graphical Mapping For createif & If then else

Hi,

I have a requirement where I have to create node based upon the below mentioned conditions.

In BAPI  return structure, we have Message ID, Message Type, Message Number  and so on...

In response, return node has to be created only when

1) Messge Type is S and message Number is 311

2) Message Type is E

And for the rest, return node need not get created in response. How to achieve this requirement with createif & If then else functions.

Please help on this..

Thanks,

Rajasekar . M
