Hi.
I think the loop will be the last step. It will be just excel.
We need to solve it for 1 user. I dont fully understand (BTW im from Czech...we lost with Sweden) what you exactly need to add as an attachment. Why do you need to be on desktop as default? If you adding full path it doesnt matter where you actually are on the disc- desktop, C:\ ... you adding: Wshell.SendKeys "C:\Users\MANUEL\Desktop\Sin titulo.png". You want attach URL or file from disc?
Moreover I think that when I added pause like WScript.Sleep 1000 in script1.vbs, it didnt work. Do it like another file a and run it in script1.vbs like in my (scriptman) method , so we know we are on the same wave.
As I said try to remove enter before Wshell.SendKeys "C:\Users\MANUEL\Desktop\Sin titulo.png" play with it, see whats it doing during script running.
As I understand - In the end you will have user id in column A and URL link in column B. When you run vba, it will add attachment to user id in -SAP, jump on another user in col A and so on. Tomorrow I try access into trsctn you are using.
