SAP S/4HANA Simple Logistics Material Master Data Changes

In 2015, SAP introduced SAP S/4HANA to the world. Organizations have been actively adopting the post-modern ERP for digitizing their business. In this blog, I will discuss the changes in Simple Logistics Material Master data from SAP ECC ERP to SAP S/4HANA. 

Changes in Simple Logistics Material Master

In terms of structure, material master is still the same. Old transactions (mm01, mm02, mm03) still exist in the SAP S/4HANA world. A few fields have been removed, new material types have been added, and the length of material has been changed. Beyond that, there is not much change from a functional perspective. 

Changes with Simple Logistics Material Ledger 

The material ledger is now mandatory for material valuation.

Changes with Foreign Trade Data 

Foreign trade data is no longer relevant in S/4HANA. It is now a part of GTS. 

Introduction of a New Material Type  

A new material type, SERV, is available in SAP S/4HANA for services. The views available are:

  • Basic data
  • Sales view
  • Purchasing view
  • Accounting

Changes in Material Master Field Length 

In ECC, the material master field length was 18 characters. Now, it has changed to 40 characters in SAP S/4HANA. But, by default, it is switched off. This means that technically, the material length can take on 40 characters but doesn’t operate that way by default. You have to check the extended material field. The menu path to check the flag for an extended material field is  

SPRO –> IMG –> CROSS-APPLICATION FUNCTIONS –> GENERAL APPLICATION FUNCTIONS –> FIELD LENGTH EXTENSION –> ACTIVATE EXTENDED FIELDS 

GO TO NEW ENTRIES AND CHECK THE FLAG 

Unless you check the flag, SAP will not use the entire 40 characters for external interface communications. When you use the interface to communicate, like sales order or purchase order using IDOC or any other mechanism, SAP still uses the old 18-character material length. BAPIs and systems which were built and are in-place have 18 characters.

For a functional consultant, the definition of material is 40 characters. The external systems do not know the definition of material. You have to check the Flag for the extended material number so that SAP starts to use the extended field for communication with external systems regarding the material master. You can also restrict the length of the material master. In addition, you can use the transaction OMSL to specify the format of material master.

These new changes in SAP S/4HANA are explained in detail during the user-training phase of SAP implementation. This enables a hassle-free transition to SAP S/4HANA. If you have any business queries, please send me an email at sakilesh@kaartech.com.
