Hi

 

I have an auto entry calculation field with value from the field "serial" which has serial increment

 

Right(Year(Get (CurrentDate));2) & "-" & Right("0"&Month(Get (CurrentDate));2) & Right(("000"&serial);4)

 

The output of which is:  yy-mm#### ; 13-110435 .... 13-110436 .........

 

How can I make calculation to reset the value "serial" in order to start from 1 at the beginning of every new month

 

Thanks 

There is a script step for "Set Next Serial Number" if your "serial" is a true auto-enter serial field.

With what I have, just creating a new record (Ctrl n) will show up the calculated value in the field "Case_ID"

 

Would this be still possible with the script? 

 

And the other thing how to auto reset the value when the month changes?

I think there are some assumptions here that are worth checking:

 

This script, attached to Case_ID with an OnObjectModify script trigger

Why would the user modify the Case_ID field?

 

Set Variable [$lastRecCalcMonth; Value:GetNthRecord (YourTable::Case_ID ; Get ( RecordNumber )-1)]

You are assuming that the most recent record is included in the current found set, and that the current sort order places it just before the current record.


Note also that the script will run (probably) while the new record is still uncommitted. A second user, creating a new record while this one is still uncommitted, will reset the serial again and create a duplicate.
