Hi,
In the standard system, the system consideres the following sources for        
the tax code (in this sequence): Reference item, contract, request for         
quotation, info record. It can also be entered manually.   
In services we do not have info records.
Furthermore, the tax code can be automatically determined via the              
condition technique.                                                           
For the determination of the tax code via the condition technique,             
condition type NAVS with assigned access sequence 003 is available in          
the standard system. With Transactions MEK1/MEK2, depending on tax             
indicators (plant, account assignment, origin) you can define        
different tax codes in the condition tables.  
In principle, you can assign this access sequence also to other                
condition types. The tax code is only transferred to the purchase order        
if class 'D' (taxes) is the condition type. If there are several               
condition types of this class in the condition schema, then the first          
condition schema which contains a tax code has priority.
