Calling Vertex from a custom program

[VenuAnumayam]

Hello Experts,

I am creating an upload program to post vendor invoices (Document Type = KR). I am using BAPI_ACC_DOCUMENT_POST for this. However the users want to call Vertex System to get the tax information and post it in the Invoice.

Can anybody please let me know how to call Vertex System from my custom program?

Thanks much for your help.

You're asking how to call a third-party software from your custom program in your system, which we know nothing about. IMHO expecting someone to do your job for free is rather naive...
