Create Multiple Deliveries based on MARA-WRKST

I have to create different deliveries based on the values of MARA-WRKST - Product Family.

for eg: MARA-WRKST has following values: ZXX, ZX1, ZXX, ZX1 and ZX1. Then there should be 1 delivery created with 2 line items of type ZXX and another delivery created with line items of type ZX1.

Please let me know how can i achieve the above.

Thank You,

Suresh
