How to add keys in Base table of Business Central

• 

With the release of Wave 1 2021 lot of new feature introduced . One of the new feature is that partners now can add keys in base table with customized field which was not possible earlier

Today we will see how we can do that

First Lets see what is happening is earlier version of business central. In earlier version we can only add the keys with the field added on table extension and we are not able to see the field available in base table for adding in keys

Look at the following example as I created one simple extension in V17 and trying to add key

Now when I try to add the keys in this table extension it will populate only those fields which are added in table extension

In New version of Business central i.e. Wave 1 2021 we can Add more keys with base table fields and use to improve the performance while retrieving or updating records

Now look at the following example for new version .Just created a simple table extension

Now when I try to add the keys in this table extension it will populate all the fields available in base table as below

So that means we can create keys with

1. Fields from base table
2. Fields from table extension

Can I create combination of fields from base table and fields from table extension ?

And the obvious answer is no and reasons are simple that both base table and table extension are two different tables in Sql server.

I hope you will find this information useful

So stay tuned for more updates.

Cheers.
