Hi Prathamesh,
As per your requirement, belwo are my suggestions
- First read the invoice data based on the invoice number entered on selection screen.
- RV_INVOICE_DOCUMENT_READ
- This Function Module will fetch all the necessary details w.r.t. the invoice number
- RV_INVOICE_DOCUMENT_READ
- Secondly, pass the collected data on to the Invoice Smartform Function Module.
Hopefully this fulfills your requirement, let me know in case you need any further inputs.
BR/Thanks
