1. SAP ECC & S4 HANA COMPARISON 1

2. SAP ECC SAP ECC- SAP ERP Central Component It’s one of sap legacy applications that originally developed to operate on a 3 rd party Db such as oracle and IBM DB2 At its core R/3 uses a client server model to store , retrieve , analyze and process data while SAP ECC runs on a web based application server. users can now access ERP data through web browsers as well as clients 2

3. SAP HANA SAP HANA is an in memory columnar database designed to accelerate sap apps and business processes that was released in 2010 Its an in memory, Column oriented database. SAP ECC is the ERP system and SAP HANA is the in memory database, designed to handle transactions and analytics 3

4. SAP S/4 HANA After SAP R/3, SAP S/4HANA is the fourth version of sap Business suite Runs on HANA Database 4

5. Changes in SAP S/4 HANA for SAP MM 5

6. Major change with sap Vendor master Material ledger is Mandatory in S4 HANA SAP S/4 HANA MRP only plans on plant and MRP area level Material number field extended up to 40 characters from 18 char New Material type SERV introduced Batch Management functionality have new transaction codes 6

7. Major change with SAP Vendor master in SAP ECC, customers and vendors are separate data objects. SAP S/4HANA integrates customers and vendors into a unified master data object called Business partners. Customer-vendor integration has several benefits, such as: One business partner can have multiple roles and addresses General data is shared across roles, which reduces your database footprint  There's less redundancy since unused data is deleted after a certain time-period 7

9. Major change with SAP Vendor master VENDOR /CUSTOMER MASTER DATA BUSINESS PARTNER Arranged mainly by Account Groups, which can be changed over time (within constraints). Customer and Vendor account groups are logical groupings of Customers and Vendors that share similar business process and system configuration requirements. While it’s possible to link a Customer and Vendor in ECC 6.0, it often resulted in an inconsistent representation. For example, consider a so-called Returns Vendor, which creates a Customer Master with a shared Business Services Address record, whereas manually linking Customer and Vendor results in two separate Business Services Address records. Arranged mainly by BP Category and BP Grouping, which cannot be changed after the BP is created. BP Category designates whether the BP is a Person, Organization, or Group. BP Groupings are logical groupings of BP that share similar business process, but not necessarily the same system configuration requirements. BP are extended to Roles as needed (e.g. Supplier, Customer), limited by customizing and authorization. A single BP can comprehensively represent a Supplier, a Customer, both, or neither, as in the case of a BP Contact Person. 9

10. Material ledger is Mandatory in S4 HANA In SAP ECC, the material ledger (ML) was optional. However, not many companies implemented the material ledger in SAP ECC due to considerations surrounding performance, effort, and aggregate tables. In SAP S/4HANA, it is mandatory to activate the material ledger. But the adoption of the material ledger has been smooth in SAP S/4HANA. This is because the considerations which were prevalent in SAP ECC are now alleviated thanks to the simplified data models in SAP S/4HANA and the Universal Journal, the ACDOCA. 10

11. Material ledger is Mandatory in S4 HANA SAP ECC SAP S4 HANA Material ledger Activation is optional Material ledger evaluates the inventory in single currency The subledger inventory is existed in the form of inventory valuation tables XBEW(H) such as EBEW, EBEWH, MBEW,MBEWH,OBEW, OBEWH,QBEW and QBEWH. We can have one company code currency and up to two parallel currencies Material ledger Activation is mandatory Material ledger evaluates the inventory in multiple currencies Sap enhanced these tables by introducing the universal journal. Parallel currencies is allow up to eight free definable currencies in the universal journal table in addition to fixed local and global currencies 11

12. SAP S/4 HANA MRP only plans on plant and MRP area level In SAP ERP, storage locations can be excluded from MRP or they can be planned separately from other storage locations. The S/4-HANA MRP only plans on plant and MRP area level. Planning on storage location level is not available in SAP S/4HANA.In S4-HANA , we need to use MRP type ND if we want to exclude the storage location from MRP and we can use MRP type VB if the materials need to be planned separately. 12

13. SAP S/4 HANA MRP only plans on plant and MRP area level SAP ECC SAP S4 HANA MRP runs occur through batch jobs during off peak hours Storage locations can either be excluded from MRP or they can be planned separately. We have to activate the MRP areas in Customizing for MRP Classic MRP(MD02) There is no need of batch jobs. MRP runs can happen in real time by leveraging the power of SAP HANA. MRP can be only be run on plant and MRP area level, it cannot be run on the storage location level MRP areas is activate by default and cannot be deactivated. MRP live (MD01) 13

14. Material number field extended up to 40 characters from 18 char SAP S/4HANA gives you the option of extending the material number from 18 characters to 40 characters. Bear in mind, though, if you turn on the extension you will have to adjust your custom code to the new material length of CHAR40.  14

15. Material number field extended up to 40 characters from 18 char SAP ECC SAP S4 HANA 15

16. New Material type SERV introduced SERV material type was introduced in SAP S/4HANA as an alternative or probably enhanced version to the DIEN material type but only for Fiori based users. Both material types could be used for the same purpose but the after affects and usage would differ. 16

17. New Material type SERV introduced SAP ECC SAP S4 HANA DIEN is received into SAP ERP as a material document without any service confirmation. It is not dependent on whether the requirements are created from SAP GUI or SAP Fiori. DIEN is used when you offer a Service to a customer e.g. in a sales order SERV materials would first require a confirmation from a responsible person who is aware about the service that has been performed by an external vendor SERV is used when you procure a Service from a vendor, e.g. in a purchase order you could also use DIEN for service procurement in case there is no requirement on recording time and work of the service provided by the vendor 17

18. Batch Management functionality have new transaction codes The transactions related to Logistics Batch Management are not available in SAP S/4HANA : MSC1, MSC2, MSC3 and MSC4. The functional equivalent in SAP S/4HANA are the following transactions: MSC1N,MSC2N,MSC3N,MSC4N The maintenance of batch master data has been completely reworked and assigned to new transaction codes.it was recommended to use the new transaction codes (MSC*N). The previous transactions and with that the belonging program code are not available within SAP S/4HANA. 18
