Enhancing 0FI_GL_4 with LSTAR (0ACTTYPE)

Dear Colleagues!

In my current project the customer needs the field 0ACTTYPE (LSTAR from BSEG table) to be uploaded with the extractor 0FI_GL_4.

For this to be possible I need to enhance the extractor, right?

Does any of you have experience with this? I have never done extractor enhancements before, and will really appreciate it if you can tell me the different steps here!

I will sign points!

Regards Silje
