Use Cases

1. If you use a SAP S/4HANA 1709 or 1610 system with Best Practice activated but without using the SAP EWM in S/4HANA, and you want to add the Best Practice for the SAP  EWM in SAP S/4HANA to an existing plant, this blog lists all the required Best Practice Org data and guides you to expedite the Basic Settings process so that you don’t need to research for the input data.
2. If you use a SAP S/4HANA 1709 or 1610 system, and you want to add the SAP EWM in SAP S/4HANA to a new or an existing plant, you replace the Best Practice Org Structure in this blog with your own and complete the basic settings by following the example.

1 Basic Settings for SAP EWM in SAP S/4HANA

SAP provides a copy of “Getting Started Guide – Basic Settings for SAP EWM in SAP S/4HANA” in the attachment of SAP Note 2494704 – SAP S/4HANA 1709: Release information and restrictions for EWM in SAP S/4HANA, and SAP Note 2347770 – SAP S/4HANA 1610: Release information and restrictions for EWM in SAP S/4HANA. Both SAP Notes have the same version of file “BasicSettings_EWMinS4_V01.pdf”.

This blog provides step-by-step screenshots based on the guide and the Best Practice Org structure.

SAP EWM in SAP S/4HANA Best Practices

SAP EWM in SAP S/4HANA provides the following 11 scope items in the Best Practice content, and this blog shows the basic settings needed for these Best Practices. For each scope item, more functional related configurations are needed. Refer to the Prerequisites Matrix for the required Building Blocks for each scope item.

NOTE:
For easy cross reference, the following paragraphs use the same paragraph numbers as in the BasicSettings_EWMinS4_V01.pdf file.

3 Warehouse Creation and Integration into the Enterprise Structure

3.1 Background Information About Warehouse Integration

The Best Practices for US Localization version for SAP EWM in SAP S/4HANA requires the following org structure. For other country localization, replace the 17 prefix by your country number. For example, instead of Plant 1710 for US, use 1010 for Germany, 2910 for Canada, 1310 for China, 3010 for Australia, etc.

3.2 Prerequisites for Warehouse Integration

Plant 1710 should have been already created in your system and an active material ledger for the valuation area has been assigned to Plant 1710.
If your plant doesn’t exist, create it and set active material ledger for your plant, see Section 3.2 in file “BasicSettings_EWMinS4_V01.pdf”.

You have to perform the following manual configuration before you could use the automated configuration tool in Section 3.4.

1. Create storage locations 171D and 171S in plant 1710.
   Customizing Path:
   Enterprise Structure → Definition → Materials Management → Maintain storage location.
   
2. Create a business partner BP1710 with predefined roles FLCU00 (FI Customer) and FLCU01 (Customer)Transaction BP
   Select create Organization icon, and enter name, Country, Language, and Save
   To add the FLCU00 BP role under the change mode, select the FLCU00 BP role, enter address, and Save.
   
   To add the FLCU01 BP role, under Change mode, select the FLCU01 BP role and save.
   You need to link the customer BP1710 to Plant 1710 via Customizing Path:
   Materials Management → Purchasing → Purchase Order → Set up Stock Transport Order → Define Shipping Data for Plants.
   Enter BP1710 in the Customer No. – Plant field.
   
3. Add FLVN00 (FI Vendor) and FLVN01 (Vendor) to BP1710
   Use transaction Code BP to change BP1710.
   Add FLVN00 BP role to Business Partner BP1710, and save.
   Add FLVN01 BP role to Business Partner BP1710, and save.
   
   You need to link BP1710 as the supplier to Plant 1710.
   In the BP transaction change mode, select the FLVN01 Supplier role, under the “Vendor – General Data” tab, enter plant 1710 in the Additional General Data section.
   

The customizing for shipping point/goods receiving point assignment, posting period settings, and cost center assignment, see Section 3.2 Page 11 in the document “BasicSettings_EWMinS4_V01.pdf”, have been set in the SAP S/4HANA configuration already.

Additional Info

The “Implementation Tool for Warehouse Integration” activates the following BC Sets. You could check their content using transaction code SCPR3.

3.5 Aligning HU Numbering

SAP Best Practice creates the following HU number ranges.

If your customer needs different HU number ranges, Section 3.5 in the pdf document, BasicSettings_EWMinS4_V01.pdf, provides setup guidelines.

3.6 Activating Transaction Data Transfer

SAP S/4HANA transfers the transaction data (inbound deliveries, outbound deliveries, and production material requests) to SAP EWM in SAP S/4HANA using queued remote function call (qRFC).

You need to allow the split of delivery so that the deliveries are split for EWM and non-EWM warehouse if an order contains items from different warehouses.

You configure Define delivery split by warehouse under customizing Path:
Logistics Execution → Shipping → Deliveries → Define Split Criteria for Deliveries → Delivery Split by Warehouse Number → Define delivery split per delivery type

Select the Delivery Split checkbox for all delivery types you use in your EWM warehouse, e.g., EL, LF, LR, etc.

In Delivery Split by Warehouse Number, choose the activity Determine delivery split per warehouse number, and select the checkbox.

For qRFC transaction data transfer, you need to generate the distribution model for the Logistics Execution warehouse:

Customizing Path:

Logistics Execution → SAP EWM Integration → Basic Setup of Connectivity → Generate Distribution Model from SAP S/4HANA to SAP EWM.

Enter data in the following fields:
Warehouse Number:                    171
Logical System of SAP EWM:    BESEWM300
Distribution Model View:             EWM (not in the help drop down list)
In the Objects screen area, select All.
In the Action screen area, select Create Entries.
Execute.

Select Yes in the following popup window.

Click the green check icon to continue the generation of the distribution model.
