Pack item to empty HU with HU_PACK idoc

[robveerman1]

For a customer we're using Inventory Management and HU-Management with idocs.
In some cases they want to pack products on an empty HU. For this to work we thought to use HU_PACK idoc.
Unfortunately we experience errors in the processing. When trying to pack items from partner location to HU we see: "Storage location 3000 is HU-managed. Entry not possible"

What I found was a difference in foreground and background processing. Where we can select 2 storage locations (from-to) in HU02 for packing, the HU_PACK idoc only supports one field for storage location.

Therefor I'm unable to define from which location I want to pack my items. What is striking is that once the HU already has some items on it, the processing of this idoc goes very well. It seems SAP then does know how to perform the from-to packing action, but for empty HU's this won't work.

After debugging the FM we have no clue how this should work, perhaps we're missing something. Anyone experience with this idoc or this process?

HU02:

HU_PACK

Anyone perhaps some experience with these idoc types?

The answer from SAP was that the HU_PACK idoc isn’t able to pack directly to a HU-managed location. You first need to use the HU_PACK idoc for packing in the non-HU location and afterwards move using WMMBXY and movement type 311/323/325 to move it over to the HU storage location.

So to summarize:

First increase stock using WMMBXY or similar idoc in NON-HU location.

Second use HU_PACK for packing. Still in the NON-HU location.

Last the transfer to the HU-location using WMMBXY or similar idoc.
