Hi,
I use shift planning to determine the work hour of my work center related with scheduling and capacity planning.
1. Define shift sequence. tcode OP4A
a. create grouping first (later will be use in work center, capacity tab detail)
b. create break schedules (where you maintain your break schedules)
c. create shift definition (here you can maintain your shift example monday to friday, saturday etc) , you can enter break rules in each shift definition
d. last create shift sequence
2. In work center IR01 or IR02, go to capacity tab and go detail
a. enter your grouping
b. go to interval and shift
Thanks,
Pravin
