Internal Order && Assets

When we create an internal order via KO01 the fields "Investment profile" and "Investment reason" on the Investments tab are mandatory fields. This leads to the following warning message:

"New order: System status requires an AuC"

and the system automatically opens the "Create asset: initial screen" screen.

We are now trying to do the same in a program, but how can I create an asset that is linked to this internal order? I already tried BAPI_FIXEDASSET_CREATE and INVEST_ASSET_MAINTENANCE but this does not seem to work.

Anybody who knows how to do this?

Kind regards,
