SAP WM & HU (nested) Stock Upload

转载自：http://scn.sap.com/docs/DOC-47864

I've recently faced the problem to upload the stock in WM where HU management is active on the storage location.

As probably you already know in SAP there is also a standard program to do this: RHUWM_INITIAL_LOAD  but in my opinion it requires a very well structured input file, and it is not always so easy to get such a file from a legacy system.

Moreover I had another complication, because our HUs were nested, and using inbound delivery didn't seem to me so “easy-to-use”, so I decided to upload the stock in another way that I'm going to explain, hoping that it could be useful for others.

The process consists in "splitting the upload process in 5 different easy steps:

1. Upload the stock in a storage location (e.g. XXXX, managed only in MM without WM nor HU).

2. Create the lower level HUs.

3. Create the upper level HUs and assign at the same time the lower level HUs to them.

4. Transfer the nested HU to the WM/HU managed storage location (e.g YYYY).

5. Transfer the SU/HU in the final destination bin.

Here is a short explanation of the above mentioned steps:

1. I wouldn't go in depth into this point since it is not the scope of this post

2. I've created an LSMW using

?Business Object (BUS3070)

?Method (CREATE)

?Message Type (HU_CREATE)

?Basic Type (HU_CREATE01)

In this LSMW you will have to indicate the data of the lower level HU:

Header data: basically packaging material, External ID

Item data: basically material, quantity, unit of measure plant, storage location, etc

3. I've created an LSMW using

?Business Object (BUS3070)

?Method (CREATE)

?Message Type (HU_CREATE)

?Basic Type (HU_CREATE01)

In this LSMW you will have to indicate the data of the upper level HU:

Header data: basically packaging material, External ID

Item data: lower level HUs

Note: for this LSMW I’ve used a hierarchical source like:

UPPER_LEVEL

            LOWER_LEVEL

Since more lower level HUs can be assigned to the same upper level HU.

4. You use a standard functionality inside HUMO to move the HUs towards another storage location or in alternative it is possible to use a LSMW by recording a VLMOVE (mov. 311)

5. Simple LSMW with recording on LT09….to transfer the SU (upper level Hus become SU in WM)

That's it.

Have a nice stock upload!

PS Please note that if you are working with single-level HUs, you should ignore the step #3
