Repeated calculations

A few weeks ago I recieved code similar to that listed below from lbass on this forum. It worked great as written. Then I copied and modified the code to what is shown.

Code:
//To be placed in the details section
whileprintingrecords;
numbervar WeightinPounds;
numbervar timeinminutes;
timeinminutes := timeinminutes + {Routing.CycleTime} + {Routing.SetupTime}/{QuoteDet.Qty1};
WeightinPounds := WeightinPounds + {Materials.PartWt}*{Materials.Qty}

As soon as I added the second formula, "timeinminutes" the "WeightinPounds" formula iterates for every instance of "timeinminutes" found in the "Routing" table.

Without "timeinminutes" the "WeightinPounds" works fine. I need both values on the report. Is there a way to calculate both without miscalculations?

There will be cases where multiple records exist in either the "Materials" table or the "Routing" table or both.

Thanks in advance.
 
You probably need to create a separate formula for timeinminutes that calculates only once per some group, but there is not enough information here to really be more specific. Sample data that shows how the data is repeating would help.

Based on your suggestion I separated the "timeinminutes" formula from the "weightinppounds" formula. First I put it in the detail section with the weight, then in its own detail section. Same reults either way. Then I tried "timeinminutes" in its own group. Then I swapped the groups. When I swapped the groups the time calculation was repeated and the weight calculation appears once. I have included some of the results below.

Each printout shows the suppressed sections so we can see what the formulas are doing. The first printout shows the correct weight calculation.

The time tally calulation is shown in minutes, the total is converted to hours. When both formulas are used none of the calculated values are correct.

Thanks again, Brad.

I don't really understand why you are using variables in the first place and I can't find your original thread. If adding the route table is causing the problem, you could add the route table and calculations related to it in a subreport.

-LB
 
I am trying to use the formulas for 3 reasons:
[ol]
[li]The running total fields won't let me do a running total of one field multilpied by another field.[/li]
[li]As I was building the report column by column it seemed OK to use a formula for time because it worked so well for weight.[/li]
[li]Our preferred format is to have all the information on one line per part number, a subreport will not allow this.[/li]
[/ol]

The original thread is here thread766-1476557. I'm not sure if anything in that thread will help now. The solution then required a correction to problems with my table links. I have revised my links in this case but I may try again.

It looks like I will probably use a sub-report as you suggest.

1-Running totals can use a formula that multiplies as the field to summarize--as long as it doesn't already contain a summary or a whileprintingrecords feature like the previous() function, for example.

2-Makes sense.

3-Using a subreport does not rule out having info on one line. A subreport can be formatted so that it displays only one field, for example. Or it can be not displayed, but pass values to a later section.
