I have created action in record. but when i am checking same from records tab by

Is the related action a quick task or a process model? If process model, the model must have a tempo-enabled start for or no start form: forum.appian.com/.../Record_Design

Its is a process model without a start form. It has a single form which is quick task and tempo enabled...

If the process model is not published, it would not show under "Related Actions". Might that be the issue? Also, are you testing as a user who has at least initiator rights to the process model?

i was passing a parameter to process so when i opened my start form and marked it as a tempo enabled. its starts working but now my start form is coming in action which in fact is used to pass value to second activity.

If you want to pass a parameter to the process model, you can delete the start form and pass the parameter using the context expression when you define the related action. Keep the variable in the model as a parameter.

Passing like below

{customerNo: rp!customerNo}

but i am getting below error

Could Not Display Form
An error occurred while applying the context for the Record Directory related action [identifier=18]. Details: Could not find variable 'rp!customerNo'

There was a similar discussion on this earlier today: forum.appian.com/.../e-95161
