Metadata config in SRM : Configure Generic Field Display on User Interface_How to get 2 custom fields in 1 row

Hello experts,

I am adding two custom fields in SC item via Metadata configuration.

I am able to see new fields in SC item details tab.

My requirement is to show both of these new fields in a single line. Currently it is coming in 2 different lines.

There is option given by SAP via "Configure Generic Field Display on User Interface" where various options are available. I tried many combinations but it is not coming properly.

I am expecting it to achieve without modifying WebDynpro as I still assume that it is achievable by Metadata config.

Can someone please help me with this.

Thanks in advance,

Shyam
