I haven't used the following function but from SAP help I believe you will need to use SAP User Exit IPRM0002. Here is the SAP Help text for this function: Example Customer Exit IPRM0002 (2) Customer exit: IPRM0002 Function module: EXIT_SAPLIPM5_002 The system calculates planned dates based on cycles. You want to adjust planned dates to meet individual requirements. For example, if the next planned date is on a Sunday or holiday, it should be moved to the next workday. For example, maintenance always on the first Monday of the month.
Try to use "Time-key date" scheduling indicator in Maintenance plan scheduling parameter and setup your package 1 mon Hope this helps.
"Time-key date" scheduling indicator can be used to ensure that your plan is always scheduled for the same date each month. For example, to ensure that it is always scheduled for the 4th of the month. However, it cannot be used to ensure that the job always occurs on the first Tuesday of the month.
Create Factory Calendars where the first Tuesday (or whatever day) is the only workday. Then create maintenance plans "Time-factory caldr". The cycle unit would be 1 day
