Excise Group and Excise Register issue

Question

Hi Friends,
We have internal order budgeting for consumables.whenever we make purchase order , the account assignment category is F and we purcahse against the particular internal order.when G/R is done the consumable material gets cosnumed against the particular interla order. ie goods receipt and the issue against the internal order with same movement type.
IF the material is exciseable then excise part 1 register shows receipt and removed quantity .please suggest how to avoid the removal entry in part 1 register. only receipt has to be updated in the part 1 not the removal ie goods issue.
and
at the same time we have std. purchasing also. we maintian one excise group for plant
and excise group i maintain consumption check box. 
at the time of register system shows only one type of procurment data . how to handle this senario.
go for other excise group need to be maintained or else one excise group is sufficeent 
pls explain step by step.

Hi Akhil,
Thanks for ur reply
i am not understood "3" their is no option in selection "3" at excise group part1 posting trigger(consumption) only.
here business line are different
senario 1: i am purchasing material for internal order (while i made GR , auto GI).
theirs is sales order or MRP direct create PO manual. (here excise group removed for consumption).
senario 2: i am purchasing material for stock (std.) (while i made GR stock goes to MMBE, after i goods issue to certain reservation based).
for std process i maintain excise group (consumption check box maintained).
in RG23a or RG23C both part1 and part2 will need to be updated.
so how can i map single excise group for two senarios.
