Purchase Requisition

1. Form Initialization & Header Details

Given the user navigates to the Purchase Requisition module,
When a new form is opened,
Then the system must auto-generate a unique Requisition No (e.g., PR-000016) and default the Requisition Date to the current date.
And the Status should default to "Draft".
And the user must be able to select the "Production" Department, Priority level, and target Warehouse from standardized dropdown menus.

2. Adding Line Items

Given the user is filling out the form,
When they click the "+ Add Line" button,
Then a new row must appear in the Line Items table.
And the user must be able to select an Item, which automatically populates the Item Desc and Item SKU Unit.
And the user must be able to input the required Item Qty.
And the user must be able to remove a line item by clicking the red trash can (Del) icon.

3. Justification & Attachments

Given the user needs to provide context for the request,
When filling out the form,
Then they can enter free-text into the Reason / Justification and Remarks by Raiser fields.
And they can upload supporting documents using the Attachments file chooser.

4. Submission & Routing

Given all mandatory fields (marked with an asterisk *) are completed,
When the user clicks "Save Requisition",
Then the system must submit the form and route it to the designated Approver.
And the Status should update from "Draft" to pending approval.
Alternate Flow: If the user clicks "Save as Draft", the form data is saved without triggering the approval workflow. Clicking "Clear" resets all fields.

5. Right-Hand Side (RHS) Tracking & Visibility

Given the user has submitted one or more Purchase Requisitions,
When they view the "Purchase Requisitions List" on the right-hand panel,
Then they should see a chronological list of their PRs summarizing the PR Number, key items requested, and submission date.
And the system must display dynamic status badges for each PR, such as:
Approve: Indicates the PR is currently pending approval from the approver.
Not Approved: (Based on the 'Approval Remarks' field) Indicates the PR was rejected.
Quotation(s) received from vendor(s): Indicates the PR was approved and the procurement team is actively sourcing it.
And the user can click "Preview" to view a read-only version of the PR, or "Edit" to modify a PR (if the status allows for edits).
