Thanks, Tiago,
You're right, my mistake about the program name. But there's still something odd about it. I find that indeed SAPLHRPAYUS_V_TXCMP does exist, but it doesn't show up in the F4 search help in SE51, and that's why I thought it didn't exist. Here's the complete list when I search for SAPLHRPAYUS* in the Repository Info System:
But if I just type in the name and trust, it turns out to be there. Next problem, though. I open up the screen 2012 in change mode, go to Layout view, and select Utilities -> Upload/Download -> as instructed, but the Upload function is greyed out for me. Only Download is active, which I don't think is what we want, is it?
So, I'm still not able to apply the Note as described.
Cheers,
Matt
