I would do this., i deactivate the code once in T77S0 table, and try to modify the name in IT0002 and see if i receive the warning message, if it comes, which means, i am getting the warning message without link with Dynamic action.
Even i realize i am getting the message only because of Dynamic action, we will have to look for the options, one thins is sure, your code is not related with any message.
Warm Regards!
