HR Allocated Checklists - How to get the transactionID for AME

Hi,

I have configured HR Allocated Checklists and it is working fine. I have also configured AME rules to assign task owners. I would like to know how is the :transactionId generated for Checklist ? In which table can I find it ?

For SSHR transaction, the transactionId is from hr_api_transactions table.

So for the Allocated Checklist, from where does it get the transaction id?

The CHECKLIST ATTRIBUTE has the following query -

SELECT AME_ATTRIBUTE_IDENTIFIER FROM PER_TASKS_IN_CHECKLIST WHERE task_in_checklist_id= substr(:transactionId,1,instr(:transactionId,'-')-1)

I would like to know from where does this transactionId come from? How is it generated ? In which table is it stored?
