I have a problem loading data into a DSO. This DSO has a bunch of date fields and is set to generate SID's upon activation. In the UR logic, some of the dates derived are found to be Zero or blank. When this gets updated into the DSO, the activation fails with the message '00000000' is not a valid date. I understand that, but my problem is the derived dates in the UR can have blank values logically and i want to show it in the report that those date fields are blank. How do i do this. This is a very important issue for us and anyone who gives a solution will be rewarded handsomely.
