Hi Sahu,
That's a good question. While creating maintenance strategy, we only define 2 character field for one line item. But when we do scheduling using IP10, if there are 2 maintenance cycles say IN and EX falling due simultaneously at the same time, it would display as IN EX in 'Scheduled Calls' tab.
Suppose there is a third cycle say FX falling due at the same time, in IP10 scheduling this will appear as IN EX FX.
Hope this clarifies!
Thanks,
Tajinder
