Recently SAP R 3 certified candidates are in dilemma. They are worried whether their present efforts will be in vain for their future career as consultant. Reason SAP will not continue their services for SAP R 3 after 2025. I have attended sessions & seen training videos of SAP S 4 HANA too. In which they have clearly stated that SAP R 3 knowledge is must for SAP HANA Consultant. I explain the same by simple example : "To get Heavy Motor Vehicle Licence, you have to get first Light Motor Vehicle Licence"

Many questions peep in the minds of recently SAP R3 Certified candidates that whether
their efforts will have importance in future after 2025 & will not be in vain.
It is clearly heard in training sessions & videos of SAP S4 HANA that to work on SAP S4
HANA , good knowledge of SAP R3 is mandatory.
I will explain in simple words :
to apply & obtain license to drive
Heavy Motor Vehicles,
the driver must be holding Light Motor
Vehicle driving license.

7. SAP R3 OR ECC SAP S4 HANA
Previously when SAP R3 -3.0c was launched
the activities were functional based during
90s
For Example –
There were separate persons for goods
receipts & goods issue in Material
Departments-
1. Goods receipts- Transaction- MB01 /
MIGO in Version 4.6C
2. Good Issue Transaction- MB1A
Were built-in or customized
3. Transfer posting- MB1B
Now in SAP S4 HANA
All the transactions of Material movements
or rolls are merged in MIGO as Present days
are of 20-20 overs cricket means of all-
rounders .
So all the transaction
Goods Receipt –
MB01, MB02, MB03 ,
MB1A- Goods Issue
MB1B- Transfer Posting
MB1C- Other Goods Receipts
MBRL- Vendor Return
MBST- Cancel Material Document
are merged in MIGO
