SAP script stops in VBA

[n_B]

Hello! I am having an issue with a script that creates STOs in SAP. When the script tries to populate the fields, the script gets an error and stops. After I perform the same tasks in SAP manually (create STO, but do not save it) and start the script again, it runs no problem and creates STOs. Can't understand what the issue is. Any ideas, please?
Thanks!
