BAPI_SALESORDER_CHANGE error V1 739 - field EDATU, WMENG

Hi people,

I tryng to use de FM BAPI_SALESORDER_CHANGE to update de field edatu and wmeng (tab schedule), but the error message V1 739 is returned. Manually by transaction VA02 the modification is possible and the fields are changeable, I have not found notes about this problem, anybody know this problem, and know how solve it ?? My second alternative is do this modification using batch input.

thanks,
