Unpacking in Delivery

Hi all,

I am working on a program where user needs to Pack and Upack the items from delivery. We are able to Pack the items but, we are not able to UNPACK items.

We have already tried with BAPI_HU_UNPACK, HU_PACKING_AND_UNPACKING FM's But we don't got any proper solution for this.

If any body worked before on this Please forward the info to me.. This is very Urgent issue....

Thanks in advance....
