SAP MM TCodes for Purchasing and Purchase Orders

Purchasing is an important part of material management. You use these SAP MM Transaction codes to do buying tasks in SAP. You may need to ask for an item, get prices from suppliers, or create a purchase order. 

Purchase Requisition TCodes. 

A purchase requisition (PR) tells the buying team what you need. ME41 creates an RFQ, ME42 changes it, and ME43 displays it. ME47 maintains supplier quotations, while ME49 compares quotations. 

It can be said that these transactions are used for creating, changing, and displaying purchase requisitions respectively.

Easy way to remember: ME51N = Create, ME52N = Change, ME53N = View.

Request for Quotation TCodes. 

A request for quotation (RFQ) asks suppliers to give you their prices. It provides several TCodes for working with requests for quotations.  Using ME41, you can create RFQ and using ME42 can make modifications to it, and with ME43 you can display it. ME47 is used for maintaining quotation while ME49 can be used for comparing quotations.

Purchase Order TCodes

A purchase order (PO) is used to tell a supplier what you want to buy. The primary purchase order TCodes are ME21N, ME22N, and ME23N. In this case, ME21N is used to create a purchase order, ME22N is used to make changes, while ME23N is used to view the document. 

Purchasing Info Record TCodes

A purchasing info record keeps details about a material and its supplier. By using this tool, you can store information about price and delivery period. It is also possible to use ME11, ME12, and ME13 to create a purchasing info record, make changes to it, and view it respectively.  These SAP MM Tcodes list assist in maintaining information concerning a particular material and its vendor. 

SAP MM TCodes for Goods Receipt and Goods Movement

When you receive materials, you need to record the stock movement in SAP MM. The same applies when stock leaves the warehouse or moves to another location.These activities are  called goods movements.

Which TCodes Are Used for Goods Movement in SAP MM?

MIGO is the main SAP MM TCode for goods movements. If you are new to SAP MM, start with MIGO. You can use it for several common inventory tasks. 

Here are some commonly used TCodes:

Goods Receipt

When you receive materials from a supplier or another source, you can use MIGO to record the goods receipt. After you post the receipt, SAP updates the stock quantity.

For example, suppose you receive 100 units against a purchase order,  Use MIGO to record the receipt in SAP MM. The stock is then updated based on the posted movement.

Goods Issue

A goods issue may happen when you send materials to production, use them for consumption, or issue them for another business need.

Stock Transfer and Transfer Posting

Stock does not always stay in one place. You may need to move it between storage locations, plants, or stock types. Depending on the SAP release and process, you can use MIGO or the legacy MB1B transaction.  The TCode available to you can depend on your SAP product and release. So, check your system before using an older transaction.

Other Inventory Movements

SAP MM also supports other stock movements. These include material document cancellation and other goods receipt activities. For example, MBST can be used to cancel a material document where the transaction is supported.

SAP MM TCodes for Inventory Management

Inventory management helps you keep track of stock in SAP MM. Inventory Management TCodes can be used to : 

• Check stock

• See material documents

• Count stock

• Find stock differences

• Manage physical inventory

Common TCodes for Inventory : 

Physical Inventory TCodes

Physical inventory means counting the items you have. You then check the count against the stock shown in SAP. A simple flow is:

MI01 → MI04 → MI07

Each TCode has a different job:

• MI01: I use it to create an inventory document.

• MI04: I use it to enter the stock count.

• MI07: I use it to process stock differences.

Simple example: You count 100 items. SAP shows 95 items. There is a difference of 5 items. The physical inventory process helps you record this difference.

Other physical inventory TCodes include:

• MI02: Change an inventory document

• MI03: View an inventory document

• MI05: Change a stock count

• MI06: View a stock count

• MI11: Perform a recount for a physical inventory document

• MI20: Create a list of stock differences

• MI21: Print inventory document.

SAP MM TCodes for Invoice Verification

After a supplier delivers the material, the next step is invoice verification. You can use specific transaction codes to create, view, park, or release supplier invoices.

Here are the main ones :

• MIRO – Enter and post an incoming supplier invoice or credit memo with reference to purchasing documents.

• MIR4 – Display a supplier invoice.

• MIR7 – Park a supplier invoice for later processing.

• MRBR – Release a blocked invoice.

SAP S/4HANA also provides SAP Fiori apps for invoice processing. So, the transaction codes and screens you use may differ based on your SAP system and setup.

SAP MM TCodes for Material Requirements Planning (MRP)

Material Requirements Planning (MRP) helps you plan the materials for business needs. It looks at things like demand, stock, and incoming materials. SAP has different TCodes for MRP. You can use them to check material needs or run MRP.

Key TCodes for MRP

• MD04: displays the current stock/requirements situation for a material

• MD01N: to run MRP Live.

For example, if you want to check the stock of a material, you can use MD04. It can show stock, incoming materials, and material needs. If you want to run MRP Live you can use the MD01N. 

The correct MRP option can depend on the correct MRP option of your SAP product and release, material settings, system settings and the MRP process your company is using.  So, before you choose an MRP TCode, check how your SAP system is set up.

SAP MM TCodes for Vendor and Purchasing Management

In SAP Material Management.  you use supplier data when you buy things. A supplier is a company or person who sells goods to you. You need supplier data to create orders and manage buying tasks.

Supplier Data in SAP S/4HANA

In SAP S/4HANA, suppliers are maintained through the Business Partner approach using transaction BP.  The options in BP may be different in each SAP system. Your system settings can affect what you see.

Vendor TCodes in SAP ERP/ECC

The following vendor master TCodes are associated primarily with SAP ERP/ECC :

• XK01 – Create a vendor

• XK02 – Change a vendor

• XK03 – View a vendor

• MK01 – Create a vendor for buying

• MK02 – Change a vendor for buying

• MK03 – View a vendor for buying

These TCodes are used in the older vendor master process.

Purchasing Info Record TCodes

A purchasing info record stores buying details. It links a supplier with a material. You can use these TCodes:

ME11, ME12, and ME13 may remain available in SAP S/4HANA GUI environments, depending on the release, configuration, and authorisation.

• BP → Manage Business Partners in SAP S/4HANA

• XK01 → Create a vendor in older SAP ERP

• XK02 → Change a vendor in older SAP ERP

• XK03 → View a vendor in older SAP ERP

• MK01 → Create a vendor for buying

• MK02 → Change a vendor for buying

• MK03 → View a vendor for buying

• ME11 → Create a purchasing info record

• ME12 → Change a purchasing info record

• ME13 → View a purchasing info record

This is important because the same task may use a different TCode in SAP S/4HANA and older SAP systems.

SAP MM TCodes for Reporting and Analysis

You use Material Management TCodes to check data. This data can be about purchases, stock, materials, or purchase requests.

Reporting and Analysis TCodes : 

• ME2N – Shows purchase orders by document number.

• ME2L – Shows purchase orders by supplier.

• ME2M – Shows purchase orders by material.

• MB51 – Shows material documents and material movements.

• MMBE – Shows the stock of a material.

How to Choose the Right SAP MM TCode for a Business Process

A long Material Management TCode list can be hard to use. You do not need to learn every code by heart. You can use a simple method to find the right TCode.

First, ask yourself these three questions:

• What am I doing?

• What data or document am I using?

• Do I want to create, change, view, process, or report something?

Next choose the SAP MM TCode for your task. Let us look at two simple examples : 

• If you want to create a material, work with material master data and use MM01 to create it.

• If you want to create a purchase order then use ME21N.

Then follow the material management process. You can also find TCodes by looking at the buying process. A simple  process is :

Purchase Requisition → Purchase Order → Goods Receipt → Supplier Invoice

The main TCodes are:

ME51N → ME21N → MIGO → MIRO

Here is what they do:

• ME51N – Create a purchase requisition.

• ME21N – Create a purchase order.

• MIGO – Record a goods receipt.

• MIRO – Enter a supplier invoice.
