AX 2009 AIF with Multiple companies

Hi,

I am working with AX 2009 for Integration process.

I am consuming the AIF webservices in C# (.net).

While processing the data (read or write) to AX the AIF is going to default company without any failure.

but my requirement is different. Using same AIF services I want to process the data for different companies also.

Can any one help me out on this requirement.

please share the navigation and c# coding that AIF supports multiple companies in AX.

please share complete navigation that AIF should support multiple companies.

Regards,
