Time Recording pop -up does not appear for RFC's and CD's

Hi Experts,

We have activated Time Recording for Incidents as well as RFC and Change Documents.

Time Recording pop-up appear for Incidents, but it does not appear for RFC's and CD's. But Time Recording can be maintained for RFC's and CD's.

Is it standard behaviour? Can we get Time Recording pop-up for RFC's and Cd's as well. If Yes, what has to be done for ZMCR, ZMAD, ZMMJ and ZMHF types.

Thanks,

Rakesh B
