Selecting Multiple Fields and adding them to custom table

I am having a table and there are few entries . I want to create a page and select multiple entries from there and I want is that selected entries move and get stored in one custom table.

It will be great if someone can guide me

I am working on dynamics 365 business central.

Create a page with a action that calls a codeunit.

The Codeunit take care of the transfer, either COPY,TRANSFERFIELD or field by field.

To select multiple entries hovering your mouse, you need to use either CurrPage.SETSELECTIONFLITER. OR SETRECFILTER
