Change partners address in BAPI_SALESORDER_CREATEFROMDAT2

Hi,

I would like to change the address of a specific ship-to party.

I've seen it is possible via SE37 with a 'B' in the addr_orig parameters.

But when I use the same parameters with the RFC call (inside my WD app) SAP return :

<b>Specify the address number or the address handler</b>

Someone can help me ?

regards,
