Hi Kapil,
For two different vendors two separate document number will be generated durin F110, so separate accounting document will be generated durin EBS upload in SAP.
But in some cases bank sends incorporated value for more than one documents in the bank file for ACH, in this case either inform to bank to send separate line for each transaction or clear the incorporated balance through FEBAN screen, here one accounting document will be generated.
Regards,
Mohammed Kalim
