Receiver Correlation????

[Former Member]

Hi Everybody!

I am implementing a BPM Scenario. I have three receieve steps in my BPM. The first one being the start process and the other two receiveing message from file adapter. The issue is when i configure these two receivers it asks for receiver correlation as a mandatory field.

First why do we need correlation?

Secondly can't I skip correlation step?

My design is receive --> Transform1 ---> Transform2 ---> Send ---> <b>Receive</b> ---> Switch ---> Transform3 --->Send ---> <b>Receive</b> -

---

> Transform4 -

---

> Send.

Dear Ashish,

correlation - When we want to collect similar kind of message we go for it. It is of collecting and we cannot Skip correlation.

Asish,

taking your scenario,

Consider your recive step is executed and the BPM is active waiting for the other file to comne in.

Before the next file comes in , if another BPM is activated becuase your recived recive1 message. Now, when the next message comes in , how does XI know which BPM instance is to be used.

Correlation is used in these cases. to corelate the messages.,

And you cannot skip correlation.
