I searched SCN and google, common idea about tabstrip in screen exit, is not possible.
But I found a way ( I dunno this is legal or illegal ). Of course not repair
Please note : For this I assume you know screen programing, exit etc.
Let me show you with example :
Adding tabstrip to Contract screens ( ME31K, ME32K, ME33K ):
First creating tabstrip screen:
Create function group : ZDUMMY
Now 2 screen as subscreen
Now lets create screen-exit screen:
Tcode : CMOD create or use existing Project for Enhancement : MM06E005 and create screen 201 for header, 211 for item.
Now adding tabstrip to layout.
Now trick point is T168 and T168F table maintenance
After all of this:
Cautions : If you try to change this table data SAP warns you
SM30 for T168 and T168F
For SD : there is V_T185 view for fcode maintenance. A little bit complex but logic is same.
