@MohanKamma please see the available resources when you carry out a PSC key word search.

To resolve the error 'posted transaction id for frame 'pyWorkPage' DOES NOT match record', you can try the following steps:

1. Reorder the actions in your set so that the flow action is the last action. This ensures that the transaction ID only changes on the last action of the set.
2. Remove any unnecessary commits in your code. Commits should only be done at the end of a transaction.
3. Ensure that the FinishAssignment activity occurs as the last step in the flow process, after all the configured actions are completed.

Please note that these are general solutions and the exact solution may depend on the specific configuration of your Pega application.

Our support document Troubleshooting stale work, validation errors, and work processing failures caused by Transaction ID mismatch  should help you analyze your issue in-depth.

Please can you log a support incident on the msp if you need this looking at by our Global Client Support team.
