Hi @darrenfloyd666 ,
Do you want to create a Calculated field in your Entity with date difference value from baseline start and baseline finish?
Based on the formula/expression that you mentioned, I think there is something wrong with it. Currently, within CDS Entity, the '-' operator could not be used to calculate the difference between two different date time values.
As an fixed solution, please take a try with the following workaround:
Action Formula Box set to following:
DIFFINDAYS(createdon, crba2_duedate)
On your side, you should type following:
DIFFINDAYS(cr1b0_baselinestart, cr1b0_baselinefinish)
Note: Above formula would calculate the Duration in Days Unit. If you want to calculate the Duration in other units, Hours, Minutes, Weeks, ..., please try the following function:
DIFFINHOURS(cr1b0_baselinestart, cr1b0_baselinefinish)
DIFFINMINUTES(cr1b0_baselinestart, cr1b0_baselinefinish)
DIFFINWEEKS(cr1b0_baselinestart, cr1b0_baselinefinish)
...
...
Note: There would have formula intelligence prompt in above Action Formula box when you type some key word, e.g. 'DIFF'
Please consider take a try with above solution, then check if the issue is solved.
Best regards,
