Immediate Retry of Failed Transactions in REFramework's

[Islam_ISmail]

Hey everyone!

I’ve got an interesting query. In the REFramework, when we’re in the “Get Transaction Data” state, if a transaction fails and I wish to retry it immediately in the next attempt, rather than waiting until the end of the queue, how should I approach this? Any precise steps or suggestions?

Hi @Islam_ISmail

Change priority on retried queue items

Use case: A dispatcher/performer model using REF. During a daily run 200-300 transactions are entered into the queue. Processing these items first-in, first-out is required A failed transaction (SE) gets one retry, managed from the orchestrator. The problem: After a queue items has failed, the retry mechanism enters it as a new, cloned queue item. This in itself is the desired way of working, but, the item ends in the end of the queue, disrupting the FIFO sequence. What I’m looking for is a…

@Islam_ISmail,

You can achieve this with this simple approach.

1. Change Argument out_TransactionItem direction to In/Out
   

   

2. Add Assign activity into Business Exception and Success Transitions Action section.
   

   
   
   
   

3. Add If condition Get Transaction Data to check if out_TransactionItem IsNot Nothing to check if need to retry last transaction.

That’s it.

Hello @ashokkarale
Thank you for your response !

Could you please explain more about the logic for these steps and how they will achieve the desired goal? I’m having difficulty grasping it.

@Islam_ISmail,

I hope you have tried to execute this in debug mode.
It’s the logic that if any Transaction Item gets executed successfully or have business exception then we are assigning nothing to the transaction item. This value will be checked in Get Transaction Data begore retrieving new queue item to process. If transaction item value have previous transaction value it means the last transaction is failed with system exception and the it will retrieve new transaction item with the same reference value.

Hope this is helpful.

Thanks,
Ashok
