How to change the start date of an element entry using an HDL

Summary:

When I attempt to change the start date of an element entry using an HDL I receive the following text in the error message, "To change the existing record to have an earlier start date, supply the ReplaceFirstEffectiveStartDate attribute with a value of Y. Use the View Business Objects task to confirm that this object supports a change to the earliest start date."

Content (required):

I attempt to change the start date using both an HDL and Spreadsheet Data Loader with the ReplaceFirstEffectiveStartDate attribute value Y but I receive the same error message. I don't see the attribute listed in the business object list but it is available in the spreadsheet data loader design.
