Error in Accounting Doc with 2 taxes

Question

Dear Gurus,
My client
requirement is that they required 3 different taxes on pricing procedures of
Sales Order to Billing Document. One is 
general sales tax i.e 17% (MWST) , other is income tax (ZIN) i.e  10%
and last one is Additional Tax i.e.1% (ZADT) . I have created condition
types ZIN and ZADT by copying MWST with same access sequence. Both Taxes ZIN
and ZADT should utilize automatically (Condition Record)  in sales document instead of any manual
entry.
First I tested the scenario with Condition Type of MWST only and it runs successfully
till creation of accounting document. Later I am testing with condition record
with ZIN but at the time of accounting document following error is coming:
Tax code OG does not appear in any G/L account item
Message no. FF753
I have
searched all the relevant queries on SCN and following steps already done in
customization from my end:
Tax type ZIN is assigned on Tax calculation procedure TAXPK with
Account Key ZIT similarly as on Sales Pricing Procedure
Create Tax Processing ZIT at T Code :OBCN  with Tax Type: Out Put Tax and Posting
Ind.:Separate line indicator
Create Tax Code :OG at Tcode :FTXP
and assign 10 in Tax Perc Rate with Tax Type :Income Tax ,Acct Key:ZIT
and Cond Type:ZIN
Assign Tax Code OG with relevant G/L on Tax Processing :ZIT at Tcode
:OB40
Assign Tax Category in relevant G/L as * (All Tax Types Allowed)
Kindly
guide which steps required rectification for proper execution of this process.
Looking
forward for your cooperation.

dear
the function of the sort key is that the setting done in the sort key will be there in the Assignment field in the accounting docuement.
the sort key is defined at the accoutn level in control tab and also at the customer master level in company code data.
if there is a mismatch between sort key defined at the customer master level and defined in the account level then system flashes this error.
u just remove the sort key from the customer master Company code data then try posting the documetr.
