5. From the sub-menu, select “Material Master” and click on “Material” to proceed to the OMNX transaction.

Step 2: Understanding OMNX Transaction Screen

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