Hello all,
I require help with setting up a workflow process which checks if the selected date & time does not fall within the range of existing date within a custom list in sharepoint 2016 onpremise.
Similarly, I asked somebody to code a JS code to validate on the form:
https://community.nintex.com/message/85369-re-how-to-check-if-a-date-time-falls-within-a-range-and-avoid-double-booking?…
can such validation also be performed when the form is submitted via workflow?? Thus is to ensure that the date does not exist in the custom list which may happen if 2 users submit a request within a time at similar time.
Cheers,
