What is SAP Transaction OMNK?

SAP Transaction OMNK (Condition Table) is a transaction code used in SAP MM to create and maintain condition tables. Condition tables are used to define and store information related to pricing, discounts, taxes, and other conditions for materials or services. OMNK allows users to customize condition tables according to their specific business requirements.

Step 1: Accessing SAP Transaction OMNK

4. Locate and click on the “Materials Management” folder.
5. From the sub-menu, select “Purchasing” and then choose “Conditions”.
6. Next, click on “Condition Table” to proceed to the OMNK transaction.

Step 2: Understanding OMNK Transaction Screen

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

• Table Maintenance: This section allows you to maintain the condition table by adding, modifying, or deleting entries.
• Selection Conditions: Here, you can define selection conditions based on which the system will retrieve the relevant entries from the condition table.
• Output Fields: This tab enables you to specify the fields that should be displayed in the output of the condition table.
• Access Sequence: The access sequence tab allows you to define the sequence in which the system should access condition records in the table.
• Index: This tab provides information about the index used for the condition table, which helps optimize the performance of condition record retrieval.

Step 3: Creating a Condition Table with OMNK

To create a condition table using OMNK, follow these steps:

1. In the “Table Maintenance” section, click on the “Create” button to create a new condition table.
2. Enter a unique key for the condition table and provide a short description.
3. Define the fields for the condition table by clicking on the “Fields” button and selecting the relevant fields from the list.
4. Specify the selection conditions, output fields, access sequence, and index according to your business requirements.
5. Once you have entered all the necessary information, click on the “Save” button to save the condition table.

Congratulations! You have successfully created a condition table using SAP transaction OMNK.

Step 4: Additional Functionality in OMNK

SAP transaction OMNK offers various additional functionalities to enhance your condition table management. Here are some notable features you can leverage:

• Change Condition Table: OMNK allows you to modify existing condition tables. You can add or remove fields, update selection conditions, or make other changes based on your evolving business needs.
• Delete Condition Table: If a condition table is no longer required, you can delete it using OMNK. However, be cautious as this action cannot be undone, and it will permanently remove all associated condition records.
• Display Condition Table: Use OMNK to display existing condition tables and review their structure, fields, and other relevant details.
• Copy Condition Table: OMNK enables you to copy an existing condition table and create a new one with similar settings. This can save time when creating similar condition tables for different purposes.
