Unpacking HU assigned to Delivery with RF (LM25)

Question

Dear,
I am experiencing problems once I try to unpack picked Materials (Transfer Order is confirmed) from a Handling Unit assigned to an Outbound Delivery by means of RF.
What I actually want to do is repack (1. unpack Materials from picked HU, 2. pack Materials into new HU with other Packaging Material).
Note that Handling Unit Management is active and Goods Issue is not yet posted for the Outbound Delivery of course.
In VL02N I can easily do this from the Packing screen (select picked HU, Empty, enter Packaging Material/create new HU, select new HU + Material, Pack).
Now when I try to unpack with LM25 (I saw on this forum this is the transaction for Unpack HU by Delivery), by entering the HU concerned, the system tells me:
Wrong object ID
for HU 1000001010
What am I doing wrong here and how can I make it work?
Thanks a lot in advance for any clues!
Kind regards,
Bart

Hi
I'm not sure if this is all related to your issues, but it might be useful info. We got an external specialist to assist with my issue and he showed me how to unpack using LM61. As some of the posts suggest, you cannot use e.g. LM25 or LM22 directly as those screens first require important input from LM61. RF Steps to Unpack:
a.) LM61->Scan Delivery and F4 Nxt
b.) F2 More
c.) F11 Unpack
d.) Scan HU
e.) F4 ByMt (Unpack Materials from HU)
f.) Scan Material in first input enabled field
g.) Type Quantity (to unpack) in second input enabled field and ENTER
(Notice that there are 2 entries for the same material/qty - the one has the checkbox selected and the other doesn't. See it like a positive and a negative)
h.) Now if you save, you'll get a success message that 'Handling unit was unpacked'
The other issue I had was to Unpack a HU child from HU parent. It is very similar to the above. The only difference is that you must scan the child HU to unpack in the last screen and enter/save. I think the idea from SAP is so as you take the HU out of the Parent HU, you scan it, enter and save after you're done unpacking. But just one important note. We have an important requirement that you cannot unpack a Loaded HU or even if the Parent HU is loaded. SAP allows this unpacking with LM61 and we had to build in those validations. Also another nice-to-know is that you can set a breakpoint at SE37 WS_DELIVERY_UPDATE_2 if you'd like to see how SAP unloads using this function.
