how to clear an invoice with program RFEBBU00

Hi All,

We have a lockbox requirement, in which we need to develop a custom program which will check the invoice amount with lockbox check amount and if amount matches within tolerance, it'll clear that invoice. Standard program RFEBLB30 is calling this program RFEBBU00. Can I use this program to clear my invoice?

Please help me on this.

Regards,
