CRMXIF_ORDER_SAVE add or update pricing conditions

Hi Experts,

I'm working in a requirement where I have to add items into a  quotation via CRMXIF_ORDER_SAVE this is working now. The problem is that I'm not able to add or update  either standar nor "Z" pricing conditions (e.g. XBRT or ZPRU). For this I use the segment  E101CRMXIF_PRCD_COND_XT and E101CRMXIF_BT_PRCD_COND where:

COND_TYPE = 'ZPRU'

COND_VALUE = 'value in numbers' e.g. 45

COND_CURRENCY = 'USD'

OBJECT_TASK = 'I'

Do you know if its possible to do it, or if anything is missing?

Thank you in advance

Regards

Donovan L.
