    Posted: 26 Nov 2015 at 4:56am
I am trying to return the minimum of a date in crystal reports XI and I get blank values returned.  I have done some investigation and it appears that crystal reports struggles to return the minimum of date fields.  From reading up it appears that a variable is the best way to achieve this.  I have no experiences of working with variables in crystal reports - so I badly need some help!
 
Now for the detail!
Originally I had a field called "Rate Set Date".  this has the following formula:
if {EVENTS.COMMENTS}<>"RATE SET" then Date(1900,01,01) else if 
{EVENTS.STATUS}="A" then Date(1900,01,01) else if {EVENTS.CCY}={transrpt.CCY} then if
{EVENTS.COMMENTS}="RATE SET"and {EVENTS.STATUS}="U" then {EVENTS.ACTION_DT}
So basically the EVENTS table has multiple records and I am only interested in those that have the COMMENTS "RATE SET" and the EVENTS.STATUS set to "U"
This was put in the details section of the report.
I have one group in the report grouped on transrpt.DEAL_NO.  I then wanted to return the minimum of the "Rate Set Date" field in the group footer for transrpt.DEAL_NO.  When the report failed to return the minimum I attempted to create a variable called "Global Variable" in the formula fields section.  This has the following formula:
 
Global DateVar ratesetdate;
 

if {EVENTS.STATUS}="U" and {EVENTS.COMMENTS}="RATE SET" and ratesetdate =minimum({EVENTS.ACTION_DT},{transrpt.DEAL_NO}) then ratesetdate={EVENTS.ACTION_DT}
 
I put this in the details section of the report.
 
I have a variable reset field called "Variabe Reset" that I have added to the Group header that has the following formula:
 
WhilePrintingRecords;
Shared DateTimeVar ratesetdate=Date(1900,01,01);
 
 
I have then got a bit stuck - I am sure I need something in the group footer but I am not sure what to put!
 
Any advice gratefully received!

use a running total
note: this will only work in a footer not a header

New Running Total
Name = whatever
Field to summarize = your date field
Type of evaluation = minimum
Evaluate= use a formula
COMMENTS = "RATE SET" and EVENTS.STATUS = "U"
Reset = on change of group (select your only group)
place in the group footer
