Hello Richard,
Study these proposals
Method1: Have 3 single cycle plans all of 3YR cycle
- First One with Operations Inspections Tasklist - with start of cycle date 01.01.2013 (Calls will be in 2016, 2019, 2022 and so on)
- Second one will be identical to first one but with stat of cycle date 01.01.2014 (Calls will be in 2017, 2020, 2023 and so on)
- Third one with Electrician duties Tasklist - with start of cycle date 01.01.2015 (Calls will be in 2018, 2021, 2024 and so on)
If you observe the calls from first 2 plans which are for the same purpose (Operations duties), we are able to skip call for 3rd year in sequence. These skipped years are having calls from the Third plan (Electrician duties).
Method2: Have 2 single cycle plans of different cycles
- First one, with 3YR cycle for Electrician duties - No issues here.
- Second one, with 1YR cycle for Inspection by Operations - Issue here is to skip the call every 3rd year. For this you need to explore a user-exit IPRM0002 (F/exit EXIT_SAPLIPM5_002 - Determination of Planned Date for Time-Based Maintenance Plans ).
- Need to work with your ABAPer
- Obviously in this case same start of cycle date will be there for these 2 plans.
Good luck
