SuchitChoudhary04/GateInwardUIAPI_WC — reverse-engineered prompt

Build me a simple SAP Business One Web Client UI API extension for a Gate Inward flow.

I want users to open it inside the SAP Business One Web Client and get a clean screen for recording incoming goods before or around GRPO processing. The screen should feel like a normal business form, with fields for vendor, purchase order or GRPO reference, vehicle number, driver name, invoice or challan number, arrival date and time, item details, quantity, remarks, and a basic status like draft, submitted, or completed.

Use the existing generated Web Client extension project as the base, keep it easy to preview locally, and make sure it can still be packaged as an MTA archive for deployment. If real SAP data connections aren’t already available, add sensible placeholders or mock data so the flow can be tested. Please keep the code organized so we can extend it later with real business rules. Look up current SAP Business One Web Client UI API docs online if needed.
