MIGO: To hide/remove few PO line items from screen

HI experts,

                 I have requirement to hide/remove few PO line items from MIGO screen. I have used (MB_MIGO_BADI~LINE_MODIFY and MB_MIGO_ITEM_BADI~ITEM_MODIFY). in case of MB_MIGO_BADI~LINE_MODIFY , there are few line items looping in the CS_GOITEM structure and line item sequence in I_LINE_ID.  If i clear single line item from CS_GOITEM from few loop iteration. Entire line item screen is showing empty and warning  msgs is showing for change of  CS_GOITEM .         

                 In case of MB_MIGO_ITEM_BADI~ITEM_MODIFY ,  there is line item structure(IS_GOHEAD). it is not allowing to clear values from

this structure.

             I have directly cleared and also  I have used field symbols to clear values from above structure. Same worning error and  hide entire line items , instead of few line items.

             Please suggest me ,if there is any alternative ways.  I am on urgent requirement.

regards,

ABDUL
