Salesforce AddMonths Function
The ADDMONTHS functionality in Salesforce can be used to add or take away a certain number of months from a specified date. This function is used to manage dates, in numerous examples related to sales and marketing in salesforce.
Here, is the syntax of the ADDMONTHS:
ADDMONTHS(object_name, number of month to be added/subtracted)
Now, Let’s discuss an example of how to use the ADDMONTHS function in Salesforce to clearly understand the concept.
Suppose, we have a custom field named “Previous Campaign Date” on a campaign object, and we get a task to calculate the upcoming date of the campaign, after a duration of one month.
So, in this case, we will use the ADDMONTHS function in a formula field and calculate the “Upcoming Campaign Date” on a campaign object.
The formula would look something like this:
ADDMONTH(Previous_Campaign_Date, 1)
It will add 1 month to the Previous_Campaign_Date field and return the resulting date by adding 1 month to it as defined in the formula field.
So, with this, we got an overview of the ADDMONTH function with syntax and examples in Salesforce. Now, we will move ahead and see some real-life applications where we utilize the ADDMONTH function in salesforce.
