How to limit the date choice in a date field

[Moacir Junior]

I need to manipulate two date fields for the following action:

Allow date filling from 1 month before the date of the request.
Example: opening in March, you can fill in the date from February onwards.
The two fields are within an MRVS and
the current reference date will be the current system date.

I would like a suggestion on how to carry out this action.

Try UI policy with relative operator. with before / After and ago and from now. @Moacir Junior

You will need to let the user select what they want , and then validate and clear the value if it doesnt meet the criteria

Solved: selected date should not be greater than 30days - ServiceNow Community

Hi @Moacir Junior 

You can simply create a UI policy for the date variable in MRVS as like below.

1. Your date of request will be same date on which the record or request is being submited.

2. so do like below:

UI Poilcy condtion > 'State date' is relative  30 days before 'created on'

UI Policy action > Clear field value 'start date'.

Add a message g_addFieldMessage('start_date', error, 'your message ');  // 'please select the date in past 30 days...'
