Intro

Some times in the Fiori app you may get blank screen. 

For FIORI apps we need to maintain the service in background. So that these app will work. At first we have to get error by finding the service name which is responsible for the respective app.

You can find the error 'Vocabulary Annotation File 'C_MRPCTRLRBYAOR_SRV_VAN' version '0001' not found on SAP GW Server' in tcode /n/IWFND/ERROR_LOG - SAP Gateway Error Log 

Find the service name from the bottom screen of tcode /n/IWBEP/REG_VOCAN by using the Vocabulary annotaion

Then go to tcode /n/IWFND/MAINT_SERVICE and click add service.

Give the system alias (LOCAL as Default) and Technical service number (Taken from above step) and click enter. Then select the service and click add service.
