Regarding tax code in condition records in SD & MM

In MM we are maintaining net price in info record and tax code is given there, when it is settle with MRKO its calculating rightly,

Eg: Info record price for XX material is 100 and tax code maintained AA as 12.5%

In FI entries after FI settlement its showing right amount as 112.5 with tax

My issue is the same cost of that material is flowing from material info record to DP90 and in to sales order with the 100rs,here I have maintained two conditions as

UTXJ and ZVAT

For this I have maintained access sequence as

UTXJ- plant/tax classification customer1/tax classification material 1 as

ZVAT- plant/sales org/material

When ever with the condition utxj comes it will take 12.5% tax and for

zvat I am directly maintaing 20% vat on few materials.

In condition records if I maintain tax code here for 12.5% as A1 and A2 as 20

In MM tax code is maintained and in SD in condition records if tax code is maintained on same cost of that material what will be the effect in accounting will be. Please guide me.
