(3) ShareShare
ReportReport
Posted on by Test user 321

Hi Guys,

I have two fields on my call distribution page.1 Delivery date 2.Delivery Date. 

& this Delivery day fields has Enum values.. Mon....Sun like this. as you can see on below screenshot.

I want ,if I select whatever date ,then date relted day will be populated on Delivery day field. 

For example : 28/03/2024 -> Thursday, 27/03/2024->Wednesday. 

But all this done through a Switch case statement in AL language.

I am writing this logic as seen on below scrrenshot.this logic is also correct.

But As per our requirement we write the code as per switch case statment.

How to do this?

    Hi,
    Also you can assign the value without case statement if the values of enum ordred from 1 to 7 (monday to sunday).
     
    "Dilvery Day" := Enum::"Dilvery Day".FromInteger(dt."Period No.");

    Hi, I think it doesn't need to be so complicated. You can get "week" just using the following standard method.
    System.Date2DWY(Date, Integer) Method
     
    Hope this helps.
    Thanks.
