Hi Bryan-SG,

Please perform below operations and test if the issue still occurs.

1. Login as an administrator.
2. Check that your user profile on the workstation has a temp folder defined and there is sufficient disk space.
3. Locate the Temp folder by going to Start -> Run and type %temp%.
4. Locate the SM_OBS_DLL folder and delete or rename it.
5. Locate the Temp folder by going to C:\WINDOWS\Temp.
6. Locate the SM_OBS_DLL folder and delete or rename it.
7. Uninstall the DI API from Add/Remove Programs.
8. Install the DI API from your latest patch with full admin rights (Run as administrator).

Kind regards,

I got new error. This is weird because it was running okay previously. It occurs here: SAPbobsCOM.Documents oDocuments = new SAPbobsCOM.Documents();

Hi Bryan-SG,

Have you installed the DI API from the same Patch package that you have installed on SAP Business One Server?

Make sure that your program is targetting to the correct DI API. Set the Target Platform as x64 and test again.

Kind regards,
