Budgetting PM Values

Dear Team,

We are generating budgeting from forecast work order's

for example we have an average usage rate as 16 and interval is 250 HR ,System is generating work order as per the PM schedule definition

But actually that equipment was utilized for 1 hour in production line so the actual service date is not as per the usage rate

example : as per the PM definition next service work order suggested falls on 22 march 18

in actual it may come in may since the equipment not run for more than 2 hours daily

Please advice

Regards,

Sai
