New option in Document Type

isn't that what the document type 'quote' is for?

Indent and Purchase Requisition functionality are the prerequisites for creating Quote. From the Quote, PO would be created.
So, thought i can add new option like "Purchase Request" in the "Document Type" field of the Purchase Header table.
Kindly advice whether adding new options in Document Type field is correct?

The best option is do not use the Purchase Header / Line tables .Create the new tables / forms to develop the Purchase Requistion / Indent.
The Purchase cycle is Purchase Requisition creation , Purchase Requisition Approval /Rejection , Purchase Enquiry creation , Creation of purchase Quote , Quote comparision and Purchase order creation.

You are wrong. The NAV requisition functionality is a "prerequisite" for the purchase order and not the quote. The purchase quote is a manually created doc for testing the vendor - in your case the "indent" (I believe you ment "intent"). The requisition on the other hand bypasses this "testing" point because it uses data set up in master tables (item, vendor) trusting the set up and creating orders directly.

So, before you put hands on NAV making any "customizations" you should read some NAV documentation to understand the standard NAV functionality in detail.

Until then take DenSter's advise.
