summary report needs one type condition

I have a summary report which has this data:

transcode     count

001              10

WOC           12

MOC            14

we have making up the orders that are summarized many order_types.

For the 001 transcode, we only want to process a specific order_type, RTR.

so i have in a formula not sure how to tell it to reject if cond. is not met.

I created a view whihc has this condition of 001 and RTR. this would maybe be easier sort of formula.

IF {CLSPAYTP.OTTRNC} = '001'

and {CLSPAYTP.OHORDT} = 'RTR'

then
