Workflow - external object

Hello,

we would like to create a new "Object Type B" as soon as the "Object type A" is approved within workflow

See pictuture:

We have configured "Object Type B" as external with SQL INSERT statement configuration.

I suppose use VBS scripting in Aprrove state - create a new object type B. Is it right?

Could you give me some hints how to handle this?

Thanks in advance,

Petr
