COND_A Idoc - Data determination

Hi,

We are sending down conditions using cond_a idocs to POS. We have a condition type that we are using data determination(http://help.sap.com/saphelp_erp60_sp/helpdata/en/06/629ee2fb9c11d199ee0000e8a5bd28/frameset.htm) . The Data key in this scenario is not sent down as part of the Idoc.

Anyone tried this before?

Regards,

Naveen
