Hi Bhatt,
Follow below sequence to complete your requirement easily,
1. Create Strategy for 500, 1000 & 2000 HR, maintain different hierarchy levels
2. Create Gen maint task list & use Strategy created in 1st step, maintain operations & assign them to packages
3. Create Measuring Counter to count HRs & don't record any document
4. Create Strategy Maint plan & maintain 0 as start counter reading.
5. Post document of reading 30000 HR against Meas Counter
6. Schedule Maint Plan -->click on "Start"--> maintain "Start of Cycle" as 30000 HR & SAVE
This will generate schedule as per your requirement. That means, your first Package will get scheduled at next odometer reading of vehicle i.e. at 30500 HR & that too after 20 days from today, see below screenshot,
Assign operations to maint packages properly in TL so that it will appear in respective maint order.
Let me know if you have any doubts.
Thanks.
