Answer 1

Hi,
please read the note 96367.
This note describes the mode of operation of the account determination             
in purchasing documents with service items. Since the most complex case            
occurs in the service entry sheet, the explanation is based on this                
document. The mode of operation in other documents is similar. Determine           
the G/L account according to the priorities listed as follows.                                                                               
1.  1st Priority:                                                                               
If you enter planned services in the service entry sheet from an                      
    assigned purchase order (account assignment category not equal 'U'),                  
    the system copies the account assignment and, in particular, the G/L                  
    account for each service line from the purchase order.
                                                                                2.  2nd Priority:                                                                               
If you enter unplanned services with reference to an assigned                         
    contract, that was stored in the limits of the purchase order, the                    
    account assignment is copied from the contract as of Release 3.1H.                    
    You can execute this mode of operation by implementing Note 74147.                                                                               
3.  3rd Priority:                                                                               
If you enter planned services in the service entry sheet from a                       
    purchase order item with account assignment category 'U', the system                  
    processes the rules stored in Customizing for the automatic account                   
    determination for the G/L account determination. The valuation class                  
    stored in the service master is taken into account here. The G/L                      
    account determined is copied into the account assignment data of the                  
    service line.                                                                               
The same procedure applies, if unplanned services are entered. The                    
    G/L account determined via the automatic G/L account determination                    
    has always a higher priority than the G/L account that may be stored                  
    in the limit of the purchase order item, because at the date of the                   
    service entry, actual services and, correspondingly, the information                  
    on the valuation class which must be considered for the G/L account                   
    assignment are available.                                                             
4.  4th Priority:   
     If you use the automatic repeat account assignment function, this            
     effects the G/L account only if no G/L account could be determined           
     according to the rules described above.                                                                               
5.  5th Priority:                                                                               
If no G/L account could be determined according to priority 1 to 4           
     in the system and unplanned services are entered, the G/L account            
     maintained in the limits is copied in the service line in case of an         
     assigned purchase order item.  
This is how the system works.
