Error in creation of Pharmacy Module

I have successfully set up ERPNext version 16 and completed the installation of Marley Healthcare on my desktop.
Now, I am trying to set up the Pharmacy module.

My approach was to use the Selling module in ERPNext version 16 and create a duplicate of it with another name called Pharmacy, so that it can be accessed as a separate Pharmacy module.

However, during this process, the Selling module does not support the duplicate option**. When I try to duplicate it, the system throws an error and the duplication is not completed.

Kindly provide a solution and guide me on the correct way to set up the Pharmacy module in ERPNext version 16.

Ok . I already joined this group.

Looks like you are trying to duplicate the Sales Order doctype - why don’t you stick to Sales Order itself?
