Calculating SLA Start Date

Hi Stacie,

Is this Time stamp an existing field? Then you just need to know the SLA based upon this existing Time Stamp field? 

yes, it is an existing field.  This will be my start date to determine my 3 day SLA, I need to be able to convert the Date, time stamp to just a date.  make sense?  For example:  1-5-17 11:05 AM would convert to 1-5-17 or 1-5-17 12:05 pm would convert to 1-8-17 for start date.  Need to convert time stamp to single day, excluding weekends and some holidays.

The first part of checking against the time of day and then if it is before 12 PM setting the SLA to today or if it is after 12 PM setting the SLA to 3 week days in the future can be achieved using a formula like the one below:

If(ToTimeOfDay([TimeStamp])<ToTimeOfDay("12 PM"), ToDate([TimeStamp]), WeekdayAdd(ToDate([TimeStamp]), 3))

Unfortunately, accounting for holidays is going to be much harder. Weekdays and Weekends are differentiated by Quick Base so a formula function like WeekdayAdd will adjust 3 days in the future skipping over weekends but holidays are not a set value in Quick Base. So the formulas will not know for example that 12/25 would be a holiday and should be skipped. Instead the formula logic would need to be hard coded with a reference for each possible holiday outcome and then given different logic. That would then need a new reference for each holiday going forward that would need to be added in. That or the table structure itself would need to be built out with a special table that helps to track and adjust for all holidays. These holidays would then also need to be put in for each year. The holidays aren't going to be as easy as the time check and weekday adjustment. 

Date/Time field works just fine with this. I just used the name Time Stamp as a stand in for the field.

I keep getting an formula syntax error.  The following is the formula.
if(ToTimeOfDay([Order Date]))<ToTimeOfDay("12 PM"),ToDate([Order Date]),WeekdayAdd(ToDate([Order Date]),3))

Try the formula below. Looks like there is just one parenthesis too many. Let me know if the below formula works better

If(ToTimeOfDay([Order Date])<ToTimeOfDay("12 PM"),ToDate([Order Date]),WeekdayAdd(ToDate([Order Date]),3))

Thank you!  Got this to work.  Now i need help with excluding Holidays.   Below is the formula to determine my SLA start date, now i need to exclude the Holidays.

If(ToTimeOfDay([Order Date])<ToTimeOfDay("12 PM"),ToDate([Order Date]),WeekdayAdd(ToDate([Order Date]),1))

I have added an additional table with holiday dates, below is the formula that i have for the date

If([SLA Start Date]<=(ToDate("January 01,2018"))and[Ship Date]>=(ToDate("January 01,2018")),1)

then i combined all holidays to below


Sum(0,[New Year's Day],[Memorial Day],[Independence Day],[Labor Day],[Thanksgiving Day 1],[Thanksgiving Day 2],[Christmas Day 1],[Christmas Day 2])

I cannot figure out the best way incorporate into the first formula, HELP!
