Hello 
KAKO stores the start, finish and break as number of seconds past 00:00:00
Example is below,
If Start is 7:12, number of seconds past 00:00:00 is calculated as
1 hour = 3600 seconds
12 mins = 60 seconds
7 hours 12 mins = 7 X 3600 + 12 X 60 = 25920
Similar calculation can be done and seconds can be calculated for finish and break,
The operating time is ( Finish - Start - Break ) X (Capacity Utilization Factor / 100)
Since it is always from mid night 00:00:00 you can determine whether it is morning 6 or evening 6, morning 6 would be 6 X 3600 seconds and evening 6 would be 18 X 3600 seconds.
| Front End | KAKO | |
| Start | 7:12:00 | 25920 |
| Finish | 16:12:00 | 58320 |
| Break | 1:00:00 | 3600 |
| Operating Time | 8 |
Regarding your problems,
Problem 1: It is not necessary to have capacity for all work centers, if no entry is found in KAKO it means no capacity has been defined for this work center. You can check this work center in CR03 if you click capacity tab it will give you an error message saying no capacity exists.
Problem 2: Check if this is pooled capacity
Problem 3: It should be 24 hours if start and end time are same
Hope this helps
