copying dates using copy control

Hi All,

I need to copy the header valid_from and valid_to date from one transaction to another.

Im using copy control to copy all header data but the date is not copied from opportunity transaction to quotation or sales transactions.

Within oppurtunity transaction the dates are working fine, since we have opport_h structure. But these values should be moved to appointment structure in quotation or sales transactions. CRM_COPY_BADI have a method DATES but this is not triggering during the copy control.

Thanx

Pandiyan.
