BAPI_OPPORTUNITY_CREATEMULTI - Problem with Quantity and Unit

Hi,

I have the requirement for creating multiple line items in Oppurtunity with BAPI BAPI_OPPORTUNITY_CREATEMULTI, I am able to create multiple line items in product tab in Oppurtunity.

But now those line items are stored Without Quantity and Units.

I have passed units in product table at fields : volume_unit, process_qty_unit, process_volume_unit_iso.

I have passed quantity in product table at fields : process_qty_unit, process_qty_num, process_qty_den.

Same quantity is also passed at schedule line item field : quantity

Can any1 please suggest?

I tried with all combinations of above possible fields.

I am not sure If i have mistaken in Input fields being passed to this bapi?

Thanks in advance.

Regards,

Narendra.
