Prasad,

Diff b/w switch & fork:

Switch step is you to decide which steps to execute inside the branches of switch step based on the conditions defined.

Fork step is used to process your steps parallely. Consider the below example,

I'm receiving three files in the Fork branhces. In the property of it u can see necessary branches , if you give it as 2 then it will come out of the fork before recieving the third file. So its upto your design how you want to design. You can give the necessary branches maximum value equals to as many branches you have in the fork.

Through Exception,

While designing the BPM , u can through the exception using Send,Transformation and Control steps. But these steps has to be placed inside block to throw exceptions. You can define the exception name in Block level, so that if you place the above steps inside the block step you can throw the exception and catch it if u needed in the Exception handler branch of block.

Hope it helps!!!

Best regards,

raj.

Hi Prasad,

<b>Fork:</b>

You use a fork when you want to continue a process in branches that are independent of each other, for example, to communicate with two systems that are independent of each other. The branches of the fork join in a union operator.

You can specify the required number of branches and then define whether the process must run through all branches, or just a particular number of branches. Furthermore, you can define an end condition for the fork

<b>Switch:</b>

You use a switch to define different processing branches for a process. The Otherwise processing branch is created automatically.

You define a condition for each processing branch (see also: Condition Editor). The condition is checked at runtime. The process is continued in the branch that is first to return the value true. If no branch returns the value true, then the process is continued in the Otherwise branch.
