I have configured a new tax ZSTX for two company codes 1000 and 2000;
I did config with following IMG tcodes;
VK11 - Domestic taxes - country PK with 1, 1 (Liable for tax, full tax).
Master Data for Customer and Material is also updated for taxes (liable for tax)
The pricing procedure is also updated properly with V/08. In company code 1000 the tax condition is determined properly but in company code 2000 the tax condition is not being determined.
