BAPI with "float" type fields: I'm trying to use BAPI_OUTB_DELIVERY_CHANGE to update info on item level. In the structure BAPIOBDLVITEMCHG for item data there are a few mandatory quantity fields which need to be given. Some of them are of the type "floating point".    Question: what is the correct way to pass values to these?

We currently do not have a "-float" option similar to the "-pack" option. We can add this in the future. Until then you need to write a small ABAP wrapper function module around the BAPI.
