[SAP] Display Hidden Tabs of PO document with Enjoyable T-code (ME21N)

Some of you maybe always prefer to use the enjoyable tcode ME21N to create a PO instead of the classic ME21. The fact is that there are some fields or even tabs hidden for the default. One of them is the field "Reason for Ordering" that may be needed by the organization.

To get it displayed when we're creating a PO document, we can configure it through these following steps:

1. Follow this link of SAP Menu: Purchasing --> Purchase Order --> Define Screen Layout at Document Level.
2. Choose the appropriate Field of Selections (e.g. ME21N)
3. Choose the Field Selection Group (or just search from the first group if you don't know the right group). For current example, select "Administrative Data, Item"
4. Tick either 'required', 'optional' or 'display' as the requirement, on the field label Reason for Ordering.
   

For your note, you must choose the appropriate field of selections that used by the PO document type you want to maintain. If you have a custom field of selection instead of the standard ME21N, then you have to maintain in both field of selections ME21N and the custom FoS.

In the example here, once you've done maintaining the display of reason for ordering, then a new tab named "Retail" that contains field Reason for Ordering, will appear when you're creating a new PO document.

This solution can also be applied for other fields or tabs that are hidden in default for enjoyable Tcodes.
