Hello Manjunath,
We can post vendor invoices with the help of FB60 t code with out having any PO Reference. FB60 is the t code to post non-PO invoices.
Go to SE16. Check BKPF table. This is table which is storing document header level infomration.
Give co.code, fiscal year, document type and T code as FB60 accordingly and also exclude other t codes as FB01 in the exclude list in T code field and then execute
Now you will get all FB60 invoices to that particular fiscal year to that desired co.code.
Now go to FBL1N - vendor line item display repor and get those details with the help of dynamic selection option.
Please do as suggested by AKPT MM.
Thanks & Regards,
Lakshmi S
