Default: blank
(meaning, don't enter anything at all)

This is the URL to which a user will be redirected to, right after login - if they have access to just this one product.

Unless you specifically wish to set a product level post-login landing page for some reason, don't use this field to specify the post-login URL. The reason for that is, if a user has access to just one product, then DAP will know that it should use this product's Post-Login URL.

But what happens if a user has access to multiple products? DAP now has no way of knowing which Product's Post-Login URL to redirect the user to, and will instead use the global setting anyway.

So, better to just set up this post-login URL at a global level, by going to Setup > Config > Post-Login URL (Global)
