GN_DELIVERY_CREATE - Need Single Inbound Delivery For multiple PO

Hi Experts,

I had a requirement, If LFDAT,LIFEX,VENDOR and STORAGE LOCATION are same then irrespective of the PO's ,  one inbound delivery needs to be created.

I am using GN_DELIVERY_CREATE, it is creating different inbound deliveries for different PO's.

Sample data.

4500001120   0010  22.12.2014     LIFEX1 100029

4500001120   0020  22.12.2014     LIFEX1 100029

4500001121   0010  22.12.2014     LIFEX1 100029

4500001121   0020  23.12.2014     LIFEX1 100029

Here, 

4500001120   0010  22.12.2014     LIFEX1 100029

4500001120   0020  22.12.2014     LIFEX1 100029

4500001121   0010  22.12.2014     LIFEX1 100029    - combining these three only one inbound delivery needs to be created.

But, it is creating as below based on PO's

4500001120   0010  22.12.2014     LIFEX1 100029

4500001120   0020  22.12.2014     LIFEX1 100029   - one inbound delivery

4500001121   0010  22.12.2014     LIFEX1 100029 - one inbound delivery

and

4500001121   0020  23.12.2014     LIFEX1 100029 - one inbound delivery.

I have already seen some post suggested to mark "X" for KZAZU field, that is also done but my issue is not solved.

Kindly let me know if you the solution for this scenario ASAP.

Thanks In Advance!!!
