Link between fields KNUMV, KPOSN in table PRCD_COND and quotation

Hi,

I want to fetch condition values from quotation created in sap crm.

As all the condition values are stored in table PRCD_COND, I am trying to access table PRCD_COND to fetch values.

Now, I am unable to get the KNUMV (Pricing Document GUID) and KPOSN (Item Number) fields.

Can anybody provide me the link between these fields and quotation, so that I can fetch values from this table.

Thanks & Regards,

Ram Jethmalani
