Problem in Set GLby in Item Master

Dear All,

I am facing problem in set GL by method in item master, In my master I have defined some items with warehouse determination, some items with Item group determination and few items with Item level determination.

but in case of items for which i have set GL by item level are automatically changes to item group as i have determined GL at item level and my item group GLs are blank system wont allow me to transact as there is no account in item group and anyway it is not desired .

anybody has faced problems like that and what would be the possible solution

Thanks,

Regards,
