If you are new to this forum, you should refer to first two threads for rules of the forum by moderator and introduction to MM/WM by Arif. Please check a brief flow of MM below.

Steps in MM Cycle:

1) Purchasing Requsition -> sent by inventory dept to purcharsing dept

2) Request for Quotation(RFQ)-> Purchasing Dept shall ask the vendors to give the quotation for the requested materials by inventory.

3) Quotation -> Quotation is sent by vendors to the company

4) Purchase order-> Based on all paramers of a quotation sent by vendors. Vendors are selected from whom the material has to be obtained. The company gives purchase order to the vendor.

5) Good's receipt -> vendors sends the goods to the company with goods receipt

6) Invoice verification -> this done based on good's receipt. this means that the ordered goods have reached or not.

7) Payment -> payment is done based on invoice verification. this is (FI/CO)

Full MM Transaction Codes Flow:


RFQ to Vendor - ME41

Raising Quotation - ME47

Comparison of Price - ME49

Creation of PO - ME21N

Goods Receipt - MIGO

Invoice (Bill PAssing) - MIRO

Goods Issue - MB1A

Physical Inventory - MI01( Create doc)

MI04 (Enter Count)

MI07 (Post)

The FI - MM integration:

First you define the g/l master records.

1) Inventory raw material a/c

2) GR/IR clearing a/c

3) Raw material consumption a/c

Above like this you define all required g/l accounts then you will go to T.CODE - OBYC

Double click BSX (this is transaction key)




These are transaction keys important.

Then you go to T CODE - OMSY (this is also important) then

Material creation T Code MM01


1) Purchase order T.code ME21N

2) Goods received " MIGO

3) Invoice verification " MIRO
