Issue with CBTA recording/execution for Purchase order Header and Item detail expansion

Hello,

We are facing lot of issue with CBTA recording/execution for Purchase order Header and Item detail expansion.

We had try to cover randon behaviour of header and Item detail ( sometime need to expand and some time collapse) with the help of Default component "CBTA_GUI_A_PRESSKEY"

Here we are using URI as :" label=DYN_4000-BUTTON; type=GuiButton; id=/app/con[1]/ses[0]/wnd[0]/usr/subSUB0:SAPLMEGUI:0019/subSUB1:SAPLMEVIEWS:1100/subSUB1:SAPLMEVIEWS:4000/btnDYN_4000-BUTTON"

And KEY as  : Ctrl+F2.

But we are not able to expand the Header detail tab.

Regards,

Ashish
