Hi Raj,
This may be possible with the help of customer exit IPRM0005.
Step1: Create one strategy with 12 packages with unit as MON. Keep hierarchy from 1 to 12.
Step2: Create Task List with strategy and assign packages to operations.
Step3: Create Maintenance Plan.
You can use your own rules to determine which maintenance packages are due next and which can be skipped(Package 7 to 12 can be skipped). If the logic in the customer exit means that packages are skipped, the system performs a start for the cycle for the maintenance plan in the background.
Example Customer Exit IPRM0005 - Maintenance Planning (CS-AG/PM-PRM-MP) - SAP Library
Example is given for counter based plan.
Also Example Customer Exit IPRM0002 (3) - Maintenance Planning (CS-AG/PM-PRM-MP) - SAP Library
- For counter-based maintenance: EXIT_SAPLIPM5_001
- For time-based maintenance: EXIT_SAPLIPM5_002

Sunil
