Hey everyone,

I have created a custom field into an existing table. I want that whenever a value is inserted to the custom field, the same value should be inserted into one of the specified existing field. Like for example in the figure below, for a specific "No." when "Net change" is 749259.10 then "Budgeted Amount" should also become 749259.10. Remember, I don't want it for the entire column but for a specific "No.". Kindly address my concern. Thank you.

No, this is not possible.

FlowFields are not physical fields that are stored in the database.

Hi,

You can not assign any value to or from of those fields as those fields are Flowfields in the table. Also if you want to you can introduce your custom field and do the following

Rec.calcfields("net Change");

Custfield := Rec."Net Change";

This is an idea but use calcfields for fields.

Thanks.

it is not working. I have attached the screenshots. You can validate whether it is correct or not and if not then provide me with your code. The EventSubscriber must be in code that's why I have created one. Thank you.

Hi
hook into the onbeforeValidate event of the Net Change field and insert the following code:

[EventSubscriber(ObjectType::Table, yourtable, 'OnBeforeValidateEvent', 'Net Change', false, false)]

local procedure fsfd(var Rec: Record yourtable)

begin

rec.Budgeted Amount:=rec.Net Change;

end;

check my answer if it helped you, thanks
