PS_HANDLE_ITM is empty when using 0SRM_TD_PO

Dear all,

We have upgraded our SRM system to 7.0. In BI, we have the old DS 0BBP_TD_PO_1 by the new Business content 0SRM_TD_PO and 0SRM_TD_PO_ACC.

In 0BBP_TD_PO_1 we are using the field ITM_SC_H_GUID in the exit ZXRSAU01, it works and ITM_SC_H_GUID is filled.

As this field do not exist in 0SRM_TD_PO we tried to use PS_HANDLE_ITM to get the same GUID of a CRM Order Object, but this field still empty.

Can anybody tel me who to fill PS_HANDLE_ITM or which field can replace it.
