Updated: Apr 9, 2023

SAP EWM Implementation Project Requirement Gathering

SAP EWM Implementation Steps



There are 6 steps of SAP implementation


1. Project Preparation

2. Business Blue Print

3. Realization

4. Final Preparation

5. Go live

6. Support

Phase Project Preparation


In SAP Warehouse Management System Implementation start with phase 1 with Project Preparation which start with requirement gathering.


Steps for Requirements Gathering


1) High level Evaluation

2) Warehouse layout

3) Questionnaire to business

4) Level 1/2 process and cross stream integration

5) Material list

6) Level 3/4/5 processes- final Business Process Master list

7) Warehouse Pictures/ Videos- tag every Pictures/ video with specific L4/L5


1. High Level Evaluation

There is lot of parameters which decides the solution to be choose.


Organizational Structure

  • Company

  • Plant

  • Storage Locations

Warehouse layout

o Shop Floor Area

o Raw Material Area

o Semi-Finished Goods Area

o Finished Goods Area

o Doors incoming or outgoing


  • High level pictures and videos asked from business stake holders to understand over all layout

  • High level layout can be plotted to have further discussion about processes and material movements

Sample Warehouse Plan Layout



Questionnaire to Business about Business Processes


? to be asked

  • Inbound process for example; from supplier, from production, subcontractor, intra/intercompany transfers

  • Production staging process- which types of materials are staged and how?

  • Internal movements- bin to bin transfer, replenishments.

  • Outbound movements- to customer, intra/intercompany transfers

  • Returns processes- Vendor/Customer returns

  • Warehouse label/form requirements

Output will be


High level understanding of overall processes, help in preparation of Business Process Master list (BPML)


Draft Process level 1&2

  • High level processes can be draft

  • Inbound process

  • Outbound process

  • Internal movements

  • Internal replenishment

  • Production staging

  • Vendor Return Process

  • Customer Return Process

Output: High level business processes & preparation of BPML processes.


This will cover cross value stream integration with

  • Procure to Pay (P2P)

  • Demand to Supply (D2S)

  • Order to Cash (O2C)

Material Movements


  • Intra company/ intercompany transfer

Also from questionnaire determine these flows to get idea about stock transfers between business affiliates.

  • Cross stream integration

From other stream for example upstream like P2P, D2S, O2C collect information to determine E2E flows.

  • Internal movements

First steps towards defining

o Storage types

o Storage sections


Material movements need to capture in matrix so that overall idea of warehouse movements will be well understood. This will help to determine different warehouse process types (WPTs).

  • Configuration Master Data

1) Configuration and EWM master data objects are to be captured in Business Process Master List (BPML). For the scoping purpose.

2) Detailed configuration template documents and data conversion documents need to be prepared separately.


Output:


Rough preparation for BPML for next level for processes

Process level- 3/4/5


With this information Business solution architect & stream leads will able to figure out the L3/4/5 processes and process variants, this is illustrated for one of the stream. This will create clear final Business Process Master list (BPML)


What is Business Process Master List?


Business Process Master List (BPML) is a standard chart that helps define an entire project to guide implementation. It defines business scenarios, business processes and transactions in the form of excel chart.

Sample BPML- example Inbound from Supplier (maintain in excel sheet)

Warehouse pictures and Videos


Collect the pictures and videos if possible.


Workshop with business


Present final BPML and scope understood the business stakeholders. In order to start the Business Blue Print (BBP) need to conduct workshop with business stakeholders.

Parallel activity it is optional can be collected from business legacy system for analysis purpose.


Data from Legacy System


1) Plant list

2) Storage location list

3) Stock report

4) Inter/intra plant movements

5) Purchase order list

6) Sales and customer order list

7) Production order list

8) Plant and internal movements

9) Outbound deliveries to customer

10) Inbound deliveries from suppliers

11) Production RM consumption


Data will give fare picture of business scenarios if anything missed during requirement gathering.
