How to add 'ANC_DAYWISE_CONC_ENABLED' in Common Lookup for Concurrent absence issue

Summary:

The system doesn't allows an overlapping absence to be added when two other absences already exist within the date range. For example, two existing absences from January 1 – 5 and January 6 – 10 and the user wants to add a third absence from January 1 – 10, the system will not allow this to happen and thrown as error stating there were overlapping absences. I got an oracle doc(2687172.1) which states I need to enable the look up code 'ANC_DAYWISE_CONC_ENABLED'.

Should I add it under the look up type 'ANC_PROC_CONFIGS'? I tried searching for this lookup types, however even this is not available in my system.
