How to create a macro for reconciling layers in AutoCAD

When opening a drawing, AutoCAD shows the following message and you would like to know of an easy way to do the reconciliation: 

Unreconciled New Layers
New layers were found that may need to be reconciled. 
 

Solution:

Layers can be reconciled by selecting them in the layers palette and then right-clicking and choosing "Reconcile layers." To automate this, you may create a macro button to do it and attach it to a toolbar:

1. Execute the CUI command.
2. In the command list, click to create a new command.

3. On the right pane, type a name for the new command (such as Reconcile).
4. Define the macro to execute.
5. Assign an icon for the new command.

6. Drag and drop the new command from the command list to a toolbar.
