I have a requirement in billing invoice to refer table
VBFA-vbeln = is_bil_invoice-hd_gen-bil_number AND
vbtyp_n = 'M'.
then go VBAK table VBAK vbeln = wa_vbfa-vbelv AND
auart = 'FD'.
if successful then print the Title as Proforma Invoice else just print Invoice .
My query is that while selecting data from VBFA it is taking a lot of time , how to reduce this time and secondly how to show the o/p as "Proforma Invoice" or "Invoice"
