DMS Document Number Assignment at Vendor Creation using Class VMD_EI_API

Dear All

I am using class VMD_EI_API to create XK01 Vendor in Background , which is working fine . Now I have a requirement to assign DMS Document Number to the Vendor at the time of its creation, using the same class VMD_EI_API . Usually we assign DMS Document Number in XK01 -> Extras -> Documents Menu Path .

Please help me in this regards .

Thanks
