ABAP Object CUAD is Inactive

While I create ABAP Dynpro report, I got "Object CUAD [program name] is Inactive" ABAP error. Although the ABAP report is active, I later realized that one of the GUI elements was left inactive which was causing the error.

Since at first I could not realize from the error message which object was causing the error message "Object CUAD is Inactive", I had made a fast search on ABAP object types. ABAP programmers can review the online help document from http://help.sap.com for ABAP object types. When I check the referred article, I see that it was a User Interface object which was causing the error message and preventing me to transport related ABAP workbench request.

I checked the GUI Status in the ABAP repository browser under the related ABAP program and see that the GUI Status object was inactive.

Activating the GUI Status immediately solved my problem enabling me to release the ABAP workbench request.
