Setting for VF01 create billing documents

Hi,

We have one scenario, we have made one package material concept just like BOM for header material we have created one material for which we have maitain BOM and for that item category as ZBOM, when we enter this parent material in Sales order all child items as per BOM coming in the SO after that we are making delivery with VL01N and in VL01N for header material i.e parent material pick qty. is 0 as we want to dispatch only child items parent material is made only to get all BOM items but after VL01N if we go for J1IJ or VF01 there also that parent material is coming delivery qty 0 but we want that is delivery qty. is zero that material should not come in J1IJ and VF01.

How to do this .

regards,
