How to make a BPM restartble at a specific point after error?

Question

Hi,
I have a somewhat very simple question.
I have a BPM that works like this:
1. receive message A
2. transform message A to message B (using valuemapping)
3. switch with a condition determining if valuemapping was succesfull for all cases.
3.1. Branch 1
3.1.1. Send message B to R/3
3.2. Branch otherwise
3.2.1. Transform message B to errorMessage
3.2.2. Send errorMessage to R/3
This is all fine and works as intended.
Now what I would like is to somehow be able to "stop" the BPM after step 3.2.2. and somehow be able to reprocess the BPM starting from step 2..
The reason for this is that if the valuemapping was unsuccesfull it means a table needs to be updated. After updating the table it would be nice if the process could just be restarted and complete with success instead of having to send data through XI once again from sending system.
I've tried to experiment with exception handling in the BPM, but have not been successfull in finding a solution that works as intended.
Hope someone can help:-)
Best regards,
Daniel

Hi Kavita,
What I want is this:
If valuemapping is unsuccesfull I want to send errorMessage to R/3. Afterwards the BPM should stop. At some point someone (or XI ifself) will try to reprocess the BPM. In this case the BPM should basically start from my previous step 2 (Transformation step with valuemapping) and then go through it all again.
I a litle unclear what exactly you want me to try - is it something like this you mean?: - but what exactly goes in the exception branch? The time part I guess can be left out in my case, since I just wanna stop right away - but still we the posibility of starting from valuemapping step when reprocessing the BPM after error.
1. receive message A
2. Block
2.1. Exception branch
2.2. Control branch
2.2.1. Loop
2.2.1.1. transform message A to message B (using valuemapping)
2.2.1.2. switch with a condition determining if valuemapping was succesfull for all cases.
2.2.1.2.1. Branch 1
2.2.1.2.1.1. Send message B to R/3
2.2.1.2.2. Branch otherwise
2.2.1.2.2.1. Transform message B to errorMessage
2.2.1.2.2.2. Send errorMessage to R/3
