Purchase Order

1. Form Initialization & Mandatory Header Details

Given the user navigates to the Purchase Order module,
When a new PO form is opened,
Then the Document Type ("Purchase Order"), Your Party Type ("Company"), and Other Party Type ("Vendor") should be auto-populated.
And the Date must default to the current date (editable).
And the system must generate or allow selection of a Document Number Prefix (e.g., "PO-") and Document Number.
And the user must be able to select the Purchase Order Status, Your Party Name (e.g., Vinayak Diamond Tools), and the vendor (To Party Name) from standard dropdowns.
And the user must select the destination Stock Received at Warehouse (Mandatory).

2. Linking the Vendor Quotation

Given the vendor (To Party Name) is selected,
When the user clicks the Quotation From Party dropdown,
Then the system should display a list of approved quotations associated with that specific vendor.
And upon selecting a quotation, the system must automatically populate the Line Items grid with the agreed-upon items, quantities, and prices from that quotation to prevent manual data entry errors.

3. Line Item Management & Calculations

Given the user is reviewing or manually adding line items,
When items are added via the "Add New Item" button or populated from a quotation,
Then the user must be able to verify or edit the Order Unit, Qty, Price (Excl GST), and Tax (%).
And the system must automatically calculate the Taxable Amt and Gross Amt for each individual line item row.
And the user must be able to delete a line item using the trash can icon.

4. Summary Totals & Currency

Given all line items are finalized,
When the user views the summary section at the bottom,
Then they must be able to select the applicable Currency.
And the system must auto-calculate the aggregate Taxable Amount, Total, apply any necessary Rounding Off, and display the final Total Amount.

5. Terms, Attachments, and Submission

Given the PO totals are correct,
When the user reviews the footer section,
Then the Term Condition text area must auto-populate with standard company terms (e.g., "1. GST Extra as applicable. 2. Goods are as per actual. 3. Warranty as per the quotation."), which the user can edit if necessary.
And the user can attach supplementary documents via the Acknowledgement Image upload and add internal notes in the Additional Note field.
And upon clicking "Submit", the system must validate that all mandatory fields (marked with *) are filled.
And upon successful validation, the PO is saved, the status is updated, and the document is ready to be transmitted to the vendor.
