Item Tab sequence change

Hello All,

At present my portfolio item level, first tab is Customer information and second tab is General information.

I want to make first tab as General information. and second tab as Customer Information.

How to do this?

I try to find component  RPM_ITEM_DETAILS_OIF but it is not present.

I try below option also but component not present

start transaction SE80,

2. Web Dynpro Comp./intf.  = FPM_OIF_COMPONENT

3. -> Component Configurations, select 'RPM_ITEM_DETAILS_OIF',

4. Then 'start the configuration'.

Is there any other way to find webdynpro component or change tab?
