Hi!
i have question about packing instruction and confirmation from decentralized WH. i have maintained POP and POF transactions for determing packing instructions. for product A upon condition system automatically add manuals X and automatically add this manuals on delivery upon creation as item 9000001 as below. (movement type 261).

all locations is linked to decentralized WH because partner must recieve this information which manuals they must add into product (depending on which country it is shipped). status od delivery is like that:

item status like this:

but when confirmation via interface get back from partner using FM BAPI_OUTB_DELIVERY_CONFIRM_DEC system issue error "Item 900001 does not exist". when using non DEC WH all is ok and system without a problem GI delivery
i debug something and cannot identify what will be the reason. all data from interface are correct so maybe this is not supported in DEC WH or?
what is alternative if this is not supported? requirements are:
- POP / POF maintaining
- automatically determination of manuals and adding item on delivery upon creation
-GI with 261 this manuals
thanks for all answers and possible solutions
