Uncomplete a job sequence in Technician Portal

Hi Gurus,

In technicians portal, if the user completes an operation in a sequence but in the wrong order there is no ‘undo’.  Although this is standard functionality, I was wondering if there was any way "out of the box" to alert the user that he is completing a sequence that is not the "next on line".

Something similar to a personalization to advise the user? Since this is OAF.... not really sure if this is possible?

This does work, however, in WIP...

Thanks,

T
