POP Up Required for Preventive Maintenance

Hi Guys,

I have a requirement where we have monthly cycles for an vehicle lets say 1M ,3 M etc now user wants to have a pop up saying that how many kilometers is entered and how many kilometres left for doing a PM on it and what Task list or Operations need to be Done.

This all is required as a pop up while working with Preventive  orders.

I thought of giving warranty type of POP up ,but how to give what steps required for it.

Any suggestions.

Thanks & Regards
