How to enable navigate between IMG activity and Transport request?

Hello,

I have create a custom node in the standard IMG (ref. Getting the basics right – Creating the perfect config table (Part 4, IMG integration) ) and everything seems to be working fine.

The TR is also updated with the IMG activity (super!)

Normally when we click on the IMG activity, we are taken to the IMG (or given a popup to decide which IMG activity to use).

But when i click the IMG activity in the TR i just get an empty popup and nothing happens

I tried to compare the custom IMG activity with standard activities, but that didn't work out. SAP documentation is of no available (who am i kidding here?)

Does anyone know how to set up the navigation between the TR and the IMG activity?

BR,

Suhas
