Extra sales tax Tallinn, Estonia, but error message FF753

Question

Hi all,
Our customer in Estonia shall have an extra sales tax to their ordinary VAT. The new sales tax will apply from 1 of June 2010 according to new legal requirements. The invoicing to customer should be like this:
Price without VAT: 100
VAT 20%: 20
Sales tax 1%: 1
Total: 121
At first I have not understood if this tax should apply on ordinary advance return for tax on sales but I guess so and why I created a new outgoing tax code with 1% VAT but to a new G/L account than the ordinary tax code. The new tax code also had accounting key MWS and condition type MWAS as the ordinary.
When my SD-consultat created an ordinary invoice the ordinary tax code with 20% (U2) was posted to. But when he later should post a new invoice he had created a new condition type for this new sales tax: ZSTX. Calculation was done correct but no accounting document was created due to error message FF753; Tax code U2 does not appear in any G/L account item (U2 was the ordinary tax code).
The tax codes look like this:
Sales tax, new, S1:
Output tax MWS 1% 110 100 MWAS
Ordinary Tax code, old, U2:
Oútput tax MWS 20% 110 100 MWAS
In invoice it is like this:
Condition type: MWSI output tax 20%
Condition type: ZSTX sales tax 1%
Calculation was correct but no accounting document according to error message FF753.
I wonder if I must create a new condition type instead of MWAS but I don´t know?
I am not good in tax and not in SD so please help me how we can post one tax amount to one tax code and one to another.

Hi Lisa,
Check the  Note 1076560 - FF 753: SD tax doc if tax code has more than one condition.
Might be it is a program error, just check.
Thanks and regards
