What is SAP Transaction OMNA?
SAP Transaction OMNA (Material Master: General) is a key transaction code used in SAP MM to create, change, and display material master records. Material master records contain essential information about materials, such as their descriptions, classifications, units of measure, and storage locations. OMNA allows users to maintain accurate and up-to-date material master data, ensuring smooth procurement and inventory management processes.
Step 1: Accessing SAP Transaction OMNA
To start using OMNA, follow these steps:
- Log in to your SAP system using your user ID and password.
- Launch the SAP Easy Access Menu.
- Navigate to the “Logistics” folder and expand it.
- Locate and click on the “Materials Management” folder.
- From the sub-menu, select “Material Master” and click on “Material” to proceed to the OMNA transaction.
Step 2: Understanding OMNA Transaction Screen
Once you have accessed OMNA, you will encounter the OMNA transaction screen, which consists of various fields and tabs. Let’s explore each of them:
- General Data: This section contains the main fields for entering general information about the material, such as material type, base unit of measure, and material group.
- Accounting Data: Here, you can maintain accounting-related information for the material, such as valuation class, price control, and valuation category.
- Purchasing Data: This tab allows you to define purchasing-related data for the material, including purchasing group, purchasing organization, and delivery tolerances.
- Sales Data: If the material is used for sales purposes, this tab enables you to specify sales-related information, such as sales organization, distribution channel, and pricing conditions.
- Plant Data: In this tab, you can define plant-specific data for the material, such as storage location, batch management, and availability check.
- Quality Management: If quality management is applicable to the material, this tab allows you to maintain quality-related information, such as inspection type, sampling procedure, and inspection plan.
- Classification: If the material needs to be classified, this tab provides fields for entering classification data, such as class type, class, and characteristic values.
- Additional Data: In this tab, you can find any additional custom fields specific to your organization’s requirements.
Step 3: Creating or Changing Material Master Records with OMNA
OMNA allows you to create new material master records or make changes to existing ones. Here’s how you can perform these actions:
- To create a new material master record, start by filling in the necessary fields in the “General Data” section:
- Material Type: Select the appropriate material type for the material being created.
- Base Unit of Measure: Specify the base unit of measure for the material (e.g., each, kilograms, liters).
- Material Group: Assign the material to a material group for classification purposes.
- Move to the relevant tabs (e.g., Accounting Data, Purchasing Data, Sales Data) and enter the required information specific to each tab.
- If you need to change an existing material master record, search for the material using the search functionality in OMNA and select the relevant record.
- Make the necessary changes in the appropriate tabs and fields.
- Once you have entered all the necessary information or made the required changes, click on the “Save” button to save the material master record.
Congratulations! You have successfully created or changed a material master record using SAP transaction OMNA.
Step 4: Displaying Material Master Records with OMNA
In addition to creating and changing material master records, OMNA also allows you to display existing records. Here’s how you can do it:
- Use the search functionality in OMNA to find the material master record you want to display.
- Select the relevant record from the search results.
- You will now be able to view all the information related to the material in the respective tabs and fields.
