Hi Abdulla,
Thanks for the link.
I was able to configure the predelivered UI and see all the colapsed trays. Now I can expand and collapse withut any problem.
However I wanted to check if my approach is correct.
I went to UI Configuration, then in FPM Browser we did WebDynpro ABAP Component Customizing.
After clicking "New" button, I was able to open the UI configuration in Edit Mode and resolved the same in UIBB properties.
I never used the Access Key as system did not ask for any access key.
Can you please let us know if we are taking correct approach.
Thanks.
