LIPS-VGPOS for Material Determination

Dear All,

We are creating an outbound delivery for a sales order with material determination line items.

In the delivery we are not getting the reference sub item number but its getting reference main item number for sub item.

Example:

Sales Order:     570000034                                             

Item No.(POSNR)         Material(MATNR)     Item Category(PSTYV)

10                                 A1                           YTAX

11                                 B1                           YTAP

Note: Sub Item(11) is relevant for pricing and billing

Delivery:  32002255

Item No.(POSNR)         Material(MATNR)     Item Category(PSTYV)     Ref Doc(VGBEL)          Ref Item(VGPOS)

10                                 A1                           YTAX                              570000034                       10                             

20                                 B1                           YTAP                              570000034                       10

We need VGPOS as 11 for sub item in the above example.

Checked copy control VTLA , check box copy item number...but didnt get it.

Kindly do the needfull.

With Regards

Azeez Mohammed
