rv_invoice_document_read demo

rv_invoice_document_read is a function module used in SAP to read invoice documents. It takes input parameters such as invoice document number and company code and returns a set of output parameters such as invoice header data, item data, tax data, and payment data.

Here is a sample code demonstrating the use of rv_invoice_document_read function module:

DATA: ls_invoice_header TYPE bapi_incinv_create_header,
      lt_invoice_items TYPE TABLE OF bapi_incinv_create_item,
      lt_invoice_taxes TYPE TABLE OF bapi_incinv_create_tax,
      lt_invoice_payments TYPE TABLE OF bapi_incinv_create_payment.

CALL FUNCTION 'RV_INVOICE_DOCUMENT_READ'
  EXPORTING
    companycode = '1000'
    invoiceno = '123456'
  IMPORTING
    invoiceheader = ls_invoice_header
  TABLES
    invoiceitem = lt_invoice_items
    invoicetax = lt_invoice_taxes
    invoicepayment = lt_invoice_payments.

In this example, we are reading the invoice document with number '123456' and company code '1000'. The function module retrieves the invoice header data into the structure ls_invoice_header, the item data into the table lt_invoice_items, the tax data into the table lt_invoice_taxes and the payment data into the table lt_invoice_payments. This data can then be further processed as per the requirements of the business scenario.
