Hi Experts

We have a data base that contains a route id, drop sequence, truck id and if it participates in our program (yes or no).  What we would like is to get a report that would show us the truck, the participants (those marked "YES") and the 3 stops (using drop sequence) before the record and 3 after so we would end up with 7 records total for each group.

Any help would be greatly appreciated.

Are you doing any other summarization in the report?

Is your data like
Route    Drop   Truck  Participant
 111         1          A1         Y
 111         2          A1         Y
 111         3          A1         Y
 111         4          A1         Y
 111         5          A1         Y

Or can the participant value change?

Can you provide some sample data?

Here is a simple sample of the data we are using.  Pretty much just what you used in your example.

So for the given data the first record is line 164 with a ys you want to see

BN1168      BX31      3390      NO
BN1169      BX41      990      NO
BN1187      BX41      1550      NO
BN1188      BX71      920      YES
BN1194      BX61      1760      NO
BN1196      BX61      1740      NO
BN1198      BX61      980      NO

If you have several YES in a row do you want to see the first 3 after the last YES?

BN1168      BX31      3390      NO
BN1169      BX41      990      NO
BN1187      BX41      1550      NO
BN1188      BX71      920      YES
BN1189      BX71      923      YES
BN1194      BX61      1760      NO
BN1196      BX61      1740      NO
BN1198      BX61      980      NO

What about the case of a YES in the 3 following records?

BN1168      BX31      3390      NO
BN1169      BX41      990      NO
BN1187      BX41      1550      NO
BN1188      BX71      920      YES
BN1194      BX61      1760      NO
BN1196      BX61      1740      YES
BN1198      BX61      980      NO


Do you want to see a separate list or restart the count to 3?

Either or will work for me.  Restarting the count would be most ideal as this would give me the maximum amount of results.

SO even though there is no correlation between the routes and truck id you want the 3 previous and subsequent records based on the order in the database?

Or are you grouping and sorting the data in the report?

Sorry, I misunderstood.  Yes there definitely a correlation between the two.   It MUST reset when it starts a new truck and doesn't include any records that aren't in that same truck.

So the data will be sorted by truck then by route then by drop?

I forgot about this last night.  I have a solution (I think) about half done.  Will try to work on it tonight.

Here is a report that seems to do what you want.  I used the data you provided in a spreadsheet.

This is fantastic!  I can't thank you enough.  Can you tell me the best way that I can print it out in the format that shows on the screen.  It seems to print your array and repeats the headers for every record.

Are you trying to print to a printer or are you exporting?

What version of Crystal?

Are you printing from the Crystal designer or an application/viewer?

Crystal Version 14.  I would like to export to Excel or comma delimited file.

Export is nearly impossible to control especially if you only really want the data.  I'll see what I can do with that report.

Thank you so much for all of your help and time.   I value your patience and knowledge and thank you for all of your help.  I am closing this question and awarding the points at this point as I just can't ask you for any more attention to this issue.  Your solution provided me with what I needed.  By exporting as a PDF and bringing it into another tool I was able to get the format required.  Not a truly All-in-One solution but it did the trick.  Without your help none of it would have been possible.  This will save us tons of time and free up some all ready squeezed bandwidth.
