Scheduling Routing to get in-house production time.

Dear Experts,

I am getting the exception message 64 in my all finish and semi-finish material. I haven't put the in-house production time and moreover I dont want to use reduction strategy as I don't want to reduce my capacity.

What I understand to shedule the routing time and update the work scheduling view as Lot dependent in house production time.

But I have tried for all finish and semi-finish( Parent and child) but still iam getting the 64 message though I have re-run the MRp after these activites.

Can you please guide me so that I can calculate my lot dependent inhouse production time.

Thanks and Regards
