SAP DMC -Transfer Data Directly from SAP System

by

In the Previous post , we saw about the SAP DMC introduction, In this post we will see the pre-requisities for migrating the data from the existing ECC System.

Do kindly review the previous post before you start on this Post.

SAP DMC – Part 1

There are many SAP projects which are now on the verse of migration. And SAP DMC till 1909 has offered only the below methods for migration

1)Transfer data using files

  • Download template file for relevant migration object
  • Populate file with relevant business data
  • Upload file to the SAP S/4HANA migration cockpit
2)Transfer data using Staging Tables
  • Staging Tables are created automatically (in an SAP HANA DB schema)
  • Populate Staging Tables with business data
  • Transfer data from Staging Tables to target SAP S/4HANA system

 

SAP Has provided this   Transfer data directly from SAP System (new with SAP S/4HANA 1909).

Transfer data from SAP ERP source system to target SAP S/4HANA system

  • Access source system through RFC connection
  • Supports data migration scenarios from other applications for example, from SAP Apparel and Footwear (SAP AFS) to SAP S/4 Fashionand Vertical Business, SAP Extended WarehouseManagement (SAP EWM) to Decentralized EWM

 

You want to migrate data from an SAP ECC 6.0 system or an to an SAP S/4HANA On-Premise system using Migration Cockpit,then one of the below Prerequisitie is to have DMIS installed in the ECC system.

The Below notes gives detailed information of the Complete Pre-Requisites.

SAP Data Migration CockPit

What is SAP DMC ?

SAP DMC  Stands for the SAP Data Migration Cockpit. SAP is Sunsetting the support of LSMW and other upload tools in the Hana Envirornment.

Earlier the Data migration was done using the LTMC. SAP offered the features of migrating or uploading the data for the S4 hana system with the predefined objects like Materail master, BOM , Routing etc.

It has options to Upload the data using files or staging tables this was available in the S4 Hana version 1909.

But From S4 Hana (OP) 2020, it is strongly bringing the SAP DMC is the only source ( Same as LTMC) but the addittional feature here is  we can directly connect the ECC system to S4 Hana system through this SAP DMC and perform the required data migration.

This also provides features to do the Mapping ( Transformation) in case if there is any changes in the master data, etc if the costcenter is changed then we can provide the source vs target and which help to create the new cost center in the S4 Hana system.

The intent of this post is to bring awareness on this tool and further topics will be detailed in the subsequent Posts.

More details about this SAP DMC is available in this link https://www.sap.com/documents/2017/07/26113ac0-c47c-0010-82c7-eda71af511fa.html and also keep watching this space for more updates on this topic

Variant Configuration – ALE Message Types

by

If you are working in a Variant configuration environment, then one of the best practices to transfer the VC – Master data between the Clients / Box is to use the ALE Methods.

The below list of message types can be a quick reference for Inward / Outward.

Outward:
MATMAS – Material master
BOMMAT -BOMs: Material BOM
CHRMAS -Class system: Characteristics master
CLFMAS -Class system: Classification master
CLSMAS -Class system: Classes master
CNPMAS -Configuration profile
DEPNET -DEPNET
ECMMAS-Engineering Change Management
KNOMAS -Global object dependencies

UPSMAS -ALE Distribution Unit (MASTER)
VFNMAS -Variant function
VTAMAS -Structure of the variant table
VTMMAS -Contents of variant table

INWARD:

MATMAS -MATM -Material Master
BOMMAT -BOMM -BOMs: Material BOM
CHRMAS -CHRM -Class system: Characteristics master
CLFMAS -CLFM -Class system: Classification master
CLSMAS -CLSM -Class system: Classes master
CNPMAS -CNPM -Configuration profile
DEPNET -DEPN -DEPNET
ECMMAS -ECMM -Engineering Change Management
KNOMAS -KNOM -Global object dependencies

UPSMAS -UPSM -ALE Distribution Unit (MASTER)
VFNMAS -VFNM -Variant function
VTAMAS -VTMAM Structure of variant table
VTMMAS -Contents of variant table

MRP – Classic MRP Vs MRP Live

by

             This Blog will feature the comparison on the selection screen parameters of the classic MRP vs MRP Live.
            As many of us will be switching from ECC to S4 Hana and MRP being one of the key functionalities of the Production planning , we will Compare the fields and also key influencing factors in this.

Comparison of Selection Fields

Reference SAP Notes:

268085    – S4TWL – MRP Live on SAP HANA – MD01N
1914010 – MD01N: Restrictions for Planning in MRP Live on HANA
1989922 –   MD01N: SAP Notes overview
2403691 – MD01n: Extension of Selection Screen (S4CORE)

Why production version is important in S4- Hana?

by

1. BOM Selection – The BOM Selection can only be done with the Production version.In ECC the Production version selection was optional which was maintained in the Material Master>MRP4>BOM.

Now In S4 the below will be only available and the BOM Selection field has been removed.

2. Sub Contracting Process:

ECC: In ECC for subcontracting process where you need to send components to the Job work vendor a Production BOM will be created with External procurement and Special procurement as 30.

S4 Hana – Along with the Material master setting , the Production version is mandatory. If PV is not maintained then in the P.req / P.Order you will not find the the BOM Explosion.

3. Conversion Report:

For Green Field Projects , this becomes one of the Key Master data.

In case if you are into Migration Project, then Running this report -CS_BOM_PRODVER_MIGRATION02 is mandatory for creation of the production version as part of conversion.

Industry 4.0

by

Industry 4.0 is current industrial Revolution that most of the companies are trying to catch up. when many of them are at various stages , with current trend it is not option but mandatory for all them to sustain in the business. This is required to increase the efficiency , increase innovation and more personalization which are few of the key drivers of current business scenarios.

Industry 4.0 is mostly managed by the connected devices. The data is collected at / very near to the source in real time, Colloborated with supporting data. It is later processed and presented for the decision makers. Along with this Artificial Intelligence, Machine learning etc help business also to prevent / predict the outcomes.

The innovation in the sensors, Processing the data with edge processors, Storing and processing the data on premise or on cloud is helping many of the enterprises to adapt the Industry 4.0.

When there are many advantages detailed , the common challenges on Business benefit (RoI), Data privacy, Legal regulation are also travelling together. Some of them take bold steps to adapt on the go.

With the communication technology already marching towards 5G+ technologies , this Industry 4.0 will be a mandatory knowledge area which needs to be upgraded / adapted to stay in the game. Let  us continue to learn and Share.
