EWM HU number range unique at mandant level

[Aurelien_Mermet-Guyennet]

Hello,

We are implementing EWM in two factories (before more). Those factories will transfer produced goods in HU to a DC center (wich aims to be on EWM) & between themselves (for semi-finish goods).

Goods will be packed within same packaging material and can be transferred within all EWM warehouses. Based on this, we need to use the same HU numbering for those HU in all factories.

Problem is, standard EWM HU numbering (number range /SCWM/HUID) is based on warehouse number :

Thus, if we have same Packaging material in all warehouses, we cannot use same number range such as HU_VEKP.

The only solution we have found is the use of BADI / SCWM/EX_CORE_HU_EXT_HUID where we can manipulate HU number at it’s creation to use number range HU_VEKP to have a unique HU number at mandant level. Prerequisite is external HU number range is the same as HU_VEKP.

However, we would like to avoir making a specific for this. Consequently, we are wondering if a standard solution exist to ensure a unique HU number at mandant level for an EWM HU creation.

We are looking forward to your answers.

Best Regards.

Hello,

I have the answers. Note 2691538 - No check against packaging material's external number range during HU creation, indicates that there is not control on external number range for HU. Thus, HU can be transferred from warehouse to warehouse without any restrictions as soon as they don't have the same number range at creation in there original warehouse.

Another option is to use a numbering system which consists of a location specific prefix + an internally created number. 
That can be achieved in different ways. 

• Own number creation logic (I think there is a BADI which can be used for that purpose)
• SAP Standard SSC numbering system 
• SAP Standard GTL numbering system. 

We are in the automotive business - so we were using the first option to generate our own GTL-Numbers but switched to the SAP Standard GTL Numbering system and are really happy with that. 
Each warehouse can then be assigned to its own number range, completely avoiding the issue mentioned above.
Also it is possible, that multiple warehouses are using the same number range object and interval, so even if they are on the same DUNS Number, there will still be no duplicates in HU-Numbers.
