Usually, when we do the development or enhancement on any MM or SD standard screen we need to know on which Action Code on each transaction refers to.
This setting is at your GUI level setting, below is the step on how to enable the Action Code displayed in your transaction. I'm using MIGO as an example.
MIGO Screen without Action Code
Step 1 Go to GUI Options from the Menu options
GUI Options Menu
SAP Gui Setting
Step 2 in the Find Setting section choose Interaction Design and Visualization 1.
Step 3 Checked Show keys within the dropdown list.
Step 4 Click Apply to reflect the changes.
Tadaaa... Below we can see the action code displayed on the left
MIGO with Action Code in the dropdown list.
In Conclusion, this setup is also beneficial for Functional and Technical Consultants, to determine Standard MM o SD screen they are referring to which Action Code.
It also helps to speed up the development time
