How To Change A Purchase Order - Purchase

Step 1)

For changing an existing purchase order you can use transaction code ME22N  (or ME22 – the old version).

Immediately after executing transaction code, system will take you to the most recent purchase order you have created, changed or viewed. If you need to change some other purchase order, you can use the option which appears in the menu

Purchase order = > Other Purchase Order.

Step 2)

SAP Quality Management (SAP QM)

SAP Quality Management (QM) assures that products meet stringent regulatory standards, are safe and uniform, and meet company product specifications. SAP QM processes are thoroughly integrated into the manufacturing process.

The Quality Management (QM) process can integrate with the following SAP modules:

The Quality Management module covers all classic quality management tasks, such as quality planning (setup of data for QM tasks), quality inspection, and quality control. SAP has several QM terms that are important to note.

Mass Creation of Material Master - Master Data

In order to create multiple materials at once, you should have access to a function like

1. eCatt tool
2. LSMW(Legacy System Migration Workbench)
3. BDC (Batch Data Communication) recordings
4. BAPI (Business Application Programing Interface)

You can also use mass maintenance transaction MM17 to create views in some cases.

But you must keep in mind that not all of the organizational levels should contain the same data (MM17 requires that all data for the materials and organizational levels you select should be the same).

Mass creation is never considered to be end users responsibility.But as a module specialist you may need to work on MM17 . In case of LSMW, BDC or BAPI, it is considered to be developers or consultants work. So you do not have to understand in detail, you just have to know the concept, and that there is this kind of possibility for mass data maintenance.

You can use MM17 for mass changing of material master data (if something can’t be accomplished by this transaction it can be done using LSMW, BDC or BAPI).

Step 1)

How to copy Material Master

In this tutorial we will go throught the process of copying an existing material master data into new material

Step 1) In transaction MM01

1. Enter material number that you want to create.
2. Enter our existing material from which we want to copy the data.
3. Click on Select Views button.

How to Change Material Master - Master Data

It may be needed to change certain option in our material master (due to the organizational changes, or changes in processes). We cannot use MM01 as that is the transaction code used only for creating views that are not maintained for certain material. In this case, we need to use MM02 and MM03 transaction codes.

In SAP transactions ending with 01 are for creating, ending with 02 for editing/changing, and the ones ending in 03 are used for viewing data without possibility to change it.

Process to change Material Master

Step 1)

1. Enter transaction code MMO2 in the command prompt
2. Enter the material number whose material master data we want to change.
   

Introduction to Master Data - SAP MM

What is Master Data ? 

Master data in SAP is used as a base for any transaction. If you are producing, transferring stock, selling, purchasing, doing physical inventory, whatever your activity may be , it requires certain master data to be maintained. We have material master data, customer master data, vendor master data, pricing/conditions master data, warehouse management master data (storage bin master data) etc.

The ones we will focus in MM module are material master and purchase info record.

Few things you should know about Master Data:

1. Material in SAP is a logical representation of certain goods or service that is an object of production, sales, purchasing, inventory management etc. It can be a car, a car part, gasoline, transportation service or consulting service, for example. outoutout
2. All the information for all materials on their potential use and characteristics in SAP are called material master. This is considered to be the most important master data in SAP (there are also customer master data, vendor master data, conditions/pricing master data etc), and all the processing of the materials are influenced by material master. That is why it’s crucial to have a precise and well maintained material master.
3. In order to be confident in your actions you need to understand material master views and its implications on processes in other modules, business transactions and a few more helpful information like tables that store material master data, transactions for mass material maintenance (for changing certain characteristics for a large number of materials at once).

What is Material Type ?

According to SAP ERP, every material has a characteristic called “material type” which is used throughout the system for various purposes.

Why is it necessary to differentiate between material types and what does that characteristic represent?

1. It can represent a type of origin and usage – like a finished product (produced goods ready for sale), semifinished product (used as a part of a finished product), trading goods (for resale), raw materials (used for production of semifinished and finished products) etc. These are some of the predefined SAP material types among others like food, beverages, service and many others.
2. We can define our custom material types if any of standard ones doesn’t fulfill our need.
