Object variable or With Block variable not set

Hi,

I'm trying to use the scheduled run of DTW to import sales orders but it doesn't work ...

I create the config file with DTW (config.xml) and saved it as described in the DTW help.

Then I created a .bat file with the command "

cd "C:\Program Files (x86)\SAP\Data Transfer Workbench\"

DTW.exe -s C:\Users\ECHES\Desktop\script_custom.xml "

But when I open .bat file DTW Opens and a message box is displayed many times stating "Object variable or With Block variable not set"

I am using SAP B1 8.82 PL08...

Thanks & Regards
