Thank you, @Angela Bayliss

Hi @Sakshi_Garg , It worked with mapping external id, I'm hopeful it can work without external id. Is that not accurate? Thanks

Hi @Sakshi_Garg, This is unique since the external id is not mapped for this import. I thought having a different vendor would cause the bills to remain separate after the import. Thanks

Hi @Tigran Shahnazaryan , In the file, the matching document numbers are listed one after the other and I use the "Add" import option. Through testing it did import as separate vendor bills if there was a different document number breaking up the matching numbers belonging to different vendors.
