How Change status of documents with ABAP

Hello.

I use transaction SOLAR01, go to document and changed status.

For example from "IN_PROGRESS" to "RELEASED" - it's OK.

But now... How I can change status in document using ABAP?

I tried to use "SA_KW_RFC_IOS_PROPERTIES_SET", but it doesn't work.

...any ideas?

Many thanks!

best regards,

Mykola.
