Splash Screen in ABAP using OO With good tips from top SDN contributor
Thomas Jung
I made 2 function modules to suit my whims.
SAP being a serious Businesss Software you cannot have too many
JPGs floating around! One or two is fun.
In Function group uou need two screens 0806 & 2009 which are
essentially blank.
I put 2 title Bars - 0806 "SAP - JOB in Progress"; 2009 - "SAP - JOB
OVER!!"
