Bucket Factor percentage influence on capacity planning
In APO you can set for resources that their finite capacity is calculated based on their Bucket capacity settings.
You also have the possibility to set a Factor %, to adjust how much from a Bucket unit effectively can be used as available capacity.
For example you set Bucket Schema to Day with a start from 00:00, and Factor to 100%:
With factor 100, you have a continous capacity for the adjacent buckets, in our example the following days will be adjacent so if you have a capacity requirement bigger than one bucket, it still can use this capacity.
But what happens if we set capacity vector less than 100%?
For example if you set it to 75%, the capacity of 24 Hours of the Bucket Unit (Day) will be 18 Hours, so you will have capacity from 00:00 to 18:00 on each of the Day units.
Which means, if you have an unbreakable capacity requirement bigger than 18:00 hours it cannot be scheduled for thiese buckets.
What you can do is to use BAdI /SAPAPO/CRESBUCKET. With using the BAdI you have the possibility to change the pre-defined schema, for example you can group 2 days together. If you have usually requirements bigger than one day, but less than two days maybe this can be a solution for you.
Or you can make two days following each other adjacent, by adjusting Bucket of the first day to start (based on our example) at 6:00, so with the 75% Factor it will last until 0:00, and the next day’s bucket will be adjacent. With that you reach continous 2 days capacity ( effectively 36 Hours with the 75% factor).
This also means that you cannot schedule bigger capacity requirement than the effective capacity of two Bucket Schema unit, if the factor is less than 100%.
If possible, and you dont want to use the BAdI mentioned, you could use a Bucket schema with bigger capacity units, like week, or month.
