What are the most frequently asked questions and answers regarding the parameter 'Activity duration stats field' in Configuration > Statistics screen?


Oracle Field Service (OFS)


I would like to know more about the 'Activity duration stats field' in Configuration > Statistics screen.


See below the most common Q & A about the 'Activity duration stats field' parameter.

Q: What is the parameter 'Activity duration stats field' used for?
In the Statistics screen you can define an activity duration key that can be used to estimate activity durations. For example, if you select aworktype, all activities of the similar type are grouped and used to estimate future activity durations for that type of activity. The parameter(s) you select in 'Activity duration stats fields' becomes the key.

Q: Why does the system let me configure more than one statistic duration key? What are the benefits?
When you have more than one key created, even though only one key is active, OFS calculates the estimated duration for each of the keys and determines the quality ranking of each key. The advantage of such feature is that before making a new key 'Active', the administrator can get an idea of how good the performance of the new key would be in comparison to the existing one. It provides you information on the impact of various parameters for statistical estimation for activity durations.

Q: What do the stars by the key mean?
The stars represent the quality of the key. The system calculates the quality of the key based on how accurate the estimation of activity durations have been or would have been, if the respective key was used for calculations. The stars ranking make it easy to see the quality of the key configured.

Q: Where can I see the calculation results for an inactive key?
You can view the results of the inactive keys for business analysis selecting the specific key in the 'Work Statistics' report. The Work Statistics report lets you evaluate the potential impact of any configured key before you activating it.

Q: How many keys can be configure?
Up to 5 (five) keys can be present in the system.

Q: What is the maximum key length and how are the fields allocated?
Please see Answer ID 9757: Activity duration key length and allocation of related fields.

Q: If I add a new key today, will the system start capturing data for this key from now on?
When the recalculation process runs, it will use all data already captured. 

Q: How often the recalculation process runs?
The recalculation process runs once a day outside of business hours to estimate durations for all key values and the quality of each existing key (Active and Inactive).

Q: Can I have more than one active key at a time?
Only 1 (one) key can be active at a time and used for activity duration estimation. You can view results of the inactive keys for analysis/comparison using the Work Statistics report.

Q: Will inactive keys affect estimation duration calculation?
Only the active key will be used for all Activity duration estimation purposes.

Q: Why does one of the inactive keys display a 'Activate' button on the right side of the key and the others inactive keys don't?
In case there is a key that has a better calculated quality than the currently active key, the 'Activate' button will be displayed up front beside the key. For all other inactive keys, the Activate option will be available within the options menu.

Q: I have edited the existing active key to include a parameter. Why does the key show as 'new'? 
Whenever a new key is added or an existing key is modified, both cases are considered as a new key in the system. The next time the calculation process runs it will give the estimated durations of all key values based on the new key.

Q: What if I add three more keys today? Will they all show the quality of the key after the next time the recalculation process runs?
OFS can calculate durations and quality of one key per day. This is done so that the performance of the system is not hampered. If you add more than one key on the same day, the additional keys will be processed on the subsequent days. If one of the new keys is active, the active one will be processed first.

Q: I have set a new key as active and saved the changes but there is a message in red stating "Changes have not been applied yet" and it indicates that the previous key is still in use. Why is that?
The key you have just activated will typically start being used the next day after the next recalculation process runs.
