Hi, Have created related action for a record. Have linked related act

Have you tried placing the context parameters values inside {} ..? Because it should be evaluated to a dictionary.

Hi Vikrant, just in case, did the process model have a start form? If so please ensure that it's deleted.

Next to the above step, ensure that the format of context is proper, for ex. {id:rp!id}. Refer documentation for much clarity.

Finally please ensure that you the user who is trying is to see the related action has no security issues, check this only if you are using a basic user for debugging.

Documentation says: Only process models that have a Tempo-enabled or SAIL start form or do not have a start form are supported as related actions. This restriction does not apply to related actions based on quick tasks.

Try using the expression for content as {PO_Number:rp!DebitMemoNo}.
Also, make sure that the given variable is set as "Pass as a parameter" in the process.
