Add negative number to AddHours in formula of a business rule

I did this with days but should work with hours and a date/time field.

[#System variable.Current Date#].AddDays(-7)

Updated via business process

Thank you. We rather not create a business process for such a thing. Looking for a way to do it via business rule.

Hello,

This method can only be implemented through a business process using C# with the ".AddHours(-1)" method.

Create another date/time field and use the set field value in the business rule with the AddHour(-1) formula. That date field will then be one hour behind start time field

There is no way to do AddHour(-1) in the formula.

Orkhan,

:(

Thanks for confirming
