CR error when using 'previous' in formula

I have a formula that compares the date an action occurred with the date of the previous record if the requester and the application were the same:


DateTimeVar e := {HD_IPR_IncidentProblem.Core_CreateDate};

DateTimeVar f := Previous({HD_IPR_IncidentProblem.Core_CreateDate});

if (OnFirstRecord)= FALSE then

if (Previous ({HD_IPR_IncidentProblem.Data_CustomersName}) = {HD_IPR_IncidentProblem.Data_CustomersName}) and (Previous ({HD_IPR_IncidentProblem.Data_ItemSubTypeCurrent} ) = {HD_IPR_IncidentProblem.Data_ItemSubTypeCurrent} ) then



This works fine on CR XI Pro on the desktop, but produces the following error when scheduled on CR Server Release 1:

Error in File S:\Business Objects\BusinessObjects Enterprise 11\Data\procSched\HADRIAN.reportjobserver\~tmp6fbc5654c726148.rpt: Error in formula <Date_Between_Changes>. 'whileprintingrecords; ' UFL 'u2ldtdif.dll' that implements this function is missing.

Can anyone explain?

Hi Andrew,

When you install the Service Pack the missing dll will get installed.

You can get the latest Service Packs at > Software Download> Business Objects Downloads.

If you can not access this check out the service pack for the Crystal Report Server at the link below.

Hope this is helpful
