HI,
But you are maintaining the condition records for Two tax condition types in VK11
1. MWS1 VAT @5%
2. MWS2 ST @12.36%
So you are maintaining VAT and ST as separate condition type therefore both the condition will come in the pricing with the same Tax code T1 so that will not deactivate the tax condition types.
Right now I am not accessing the system therefore can't test it but I think it should work.
Please check and see what you are getting.
Thanks,
Suman$
