What is SAP Transaction ME01?

SAP Transaction ME01 (Maintain Source List) is a transaction code used in SAP MM to create and maintain source lists for materials. A source list contains information about the approved vendors or supply sources for a particular material. ME01 allows users to define and manage the list of vendors or supply sources from which materials can be procured.

Step 1: Accessing SAP Transaction ME01

To start using ME01, follow these steps:

1. Login to your SAP system using your user ID and password.
2. Launch the SAP Easy Access Menu.
3. Navigate to the “Logistics” folder and expand it.
4. Locate and click on the “Materials Management” folder.
5. From the sub-menu, select “Purchasing” and then choose “Source List”.
6. Next, click on “Maintain Source List” to proceed to the ME01 transaction.

Step 2: Understanding ME01 Transaction Screen

Once you have accessed ME01, you will see the ME01 transaction screen, which consists of various fields and tabs. Let’s explore each of them:

• Header Data: This section contains the main fields for entering general information about the source list, such as the material, plant, and purchasing organization.
• Item Overview: Here, you can view and manage the line items of the source list. Each line item represents a vendor or supply source for the material.
• Document Overview: This tab provides an overview of the entire source list, including its header and item details.
• Validity Periods: The validity periods tab allows you to define the start and end dates for each vendor or supply source in the source list.
• Additional Data: In this tab, you can find any additional data specific to your organization’s requirements, such as purchasing info records or quotas.
• Status: The status tab shows the current status of the source list, indicating whether it is active or inactive.

Step 3: Creating a Source List with ME01

To create a source list using ME01, follow these steps:

1. Start by filling in the necessary fields in the “Header Data” section:

   • Material: Enter the material code for which you want to create a source list.
   • Plant: Select the plant for which the source list is being created.
   • Purchasing Organization: Choose the purchasing organization responsible for procuring the material.

2. Move to the “Item Overview” tab and enter the following details for each vendor or supply source:

   • Vendor: Enter the vendor code or use the search function to find it.
   • Source List Usage: Specify the usage of the source list, such as “Standard” or “Subcontracting”.
   • Valid From/To: Define the validity period for the vendor or supply source in the source list.
   • Other relevant information: Enter any additional details, such as purchasing info records or quotas.

3. Once you have entered all the necessary information, click on the “Save” button to create the source list.

Congratulations! You have successfully created a source list using SAP transaction ME01.

Step 4: Maintaining and Updating Source Lists

In addition to creating source lists, ME01 also allows you to maintain and update existing source lists. Here are some key functionalities:

• Display Source List: Use ME01 to display existing source lists by entering the material code and other relevant criteria. This allows you to review the approved vendors or supply sources for a particular material.
• Change Source List: ME01 enables you to modify existing source lists. You can edit fields such as vendors, validity periods, or other relevant details. Simply enter the material code and make the necessary changes.
• Delete Source List: If a vendor or supply source is no longer valid, you can delete it from the source list using ME01. Enter the material code and the vendor to be deleted, and confirm the deletion.
• Copy Source List: ME01 also provides the option to copy source lists from one material to another. This can save time when creating similar source lists for multiple materials.
