Sort option

Question

i have a formula that retreives a date time stamp based upon a modification to the data.
i created a datepart formula to retreive the month, day , year, and time
then concatenated it to use in the sort option
i am unable to use this formula as a group of a sort option.
this is my formula(same for day, month, year, time)
if {@modification type}='O' then (datepart('d',{PR_ITEM_HIST_RPT;1.CREATE_DATE})  )
else if {@modification type}='U' and {PR_ITEM_HIST_RPT;1.Pack_chnge_date}>={PR_ITEM_HIST_RPT;1.CHANGE_DATE}
then (datepart('d',{PR_ITEM_HIST_RPT;1.Pack_chnge_date}))
else if {@modification type}='U' and {PR_ITEM_HIST_RPT;1.Pack_chnge_date}<={PR_ITEM_HIST_RPT;1.CHANGE_DATE}
then (datepart('d',{PR_ITEM_HIST_RPT;1.CHANGE_DATE}))
then i use this
totext({@datepart mnth}&{@datepart day}&{@datepart year}&{@time part})
what would be hindering my use of this?

Answer 1

Not sure why it does not work, but I suspect it has to do with your concantenation.
Instead of breaking out the date components and then concantenating, try using the following formula to generate your sorting factor:
      ToText(Date(field))
