G/L account should come automatically in ML 81N

Question

Dear all;
I have one requirement as belo:
For Service procurement the service G/L account should automatically come at the time of PO creattion.
I have configured as below
1 ) Created Valueation Class 3200 for service in development client.
2) Created Material group for Service : Service
3)  Assign the material Group in the " Entry Aids without material master to valueation class 3200
4)  OBYC:
   For GBB :
General Modifier          Valueation Class         G/L account
VBB                             3200                              18380100
For WRX
Valuation Modifier                 Valueation Class              G/L   account
1101                                           Blank                            10800300
Service A/c   18380100
Clearing A/c  10800300
Still the G/L account is not coming automatically in the PO creation time for service.
Kindly Suggest.
