How to manage use or not use SOVOS/VERTEX external system with several company codes in USA

[kim_hyun_jun]

Dear FI and US tax Expert,

I have a question for tax process in USA with SOVOS tax external system. Our company use only one client(100) and one S4HANA system. But there are so many company codes in S4HANA system.

For example, we have four company code in USA.

1000 : Company1 in USA / Use SOVOS tax external system.

2000 : Company2 in USA / Use SOVOS tax external system.

3000 : Company3 in USA / Not use SOVOS tax external system.

4000 : Company4 in USA / Not use SOVOS tax external system.

The tax procedure TAXUSX is assigned to country code US. And the country code US is assigned to four country code. And four company code have a same tax procedure TAXUSX. The tax procedure TAXUSX link to SOVOS external tax system.

I want to use SOVOS external tax system for only two company code (1000, 2000). And for the other company code, i want to post FI document with tax code by manually.

If you guys have same experience, please tell me how to do it.

Thanks

Jun
