Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

          RE: db structure help


          Are you talking about how to set up a database table, how to divide the individual columns into normalized sets, or how to work your business process into an activity that a databsse could do? Perhaps your distraction by these sub tasks is why you can't get pointed in any one direction.

            Thanks to all for their replys
            Sorry for the criptic message, frustration and late hours are contributing factors.
            I'll try to layout as much of it as I can....
            A little background first
            This system tracks paint usage in a manufacturing environment to fulfill EPA tracking and reporting requirements.
            Each product used has a tracking requirement of daily, monthly, annual.
            Each product has basically two items that are tracked (VOC volitale organic compounds) and (HAP hazardous air pollutants (could be from 0 to many compounds. Feds & state determine which haps are tracked)) Each are tracked for daily,monthly and annual totals.

            Daily usage is enter and calculations performed (where the problem lies)

            1) Transaction Tables
            Usage Header
            Id number
            Usage Detail (linked to header via id number)
            Id number
            Product Id number

            2) Reference Tables
            Product Reference (a lookup in usage detail)
            Product Id Number
            Other data such as specific gravity, mfg etc.
            Product Hap Reference (defines the haps in our products)
            Product Id Number
            CAS Number
            HAP Reference Data (List of HAPS from state / feds)
            CAS number
            HAP Name
            Other data

            Example: Product ID: 1DX008 Name: Off-White
            Contains these haps
            Name CAS Percent
            Ethylbenzene 100-41-4 .05
            Xylene 1330-20-7 .09
            Toluene 108-88-3 .01

            I can enter and pull all the data / calculations I need except for one consistant snag.....
            The monthly totals (via a report) are used in another report and i cannot figure out a way to save these totals for further use. All calculations are multilayer calculations and grouped by month / by product.

            I probably didn't lay it out very well but would appreciate any insights or help

              To quote the (im)famous Barry R., extract, sort and report.

              In other words, use a script to write your records to another table. If necessary, use a variable to keep track of specific information in your script, and write that variable to your table. Then base your report on that table.
              Also include in the target table the relevant date (perhaps the last date of every month). Then you can later use that data for other reports.

              Hope this helps.

                Thought of that, but the multible HAPS associated with each product has me stumped.
                I was trying to write a child table for each product used that would contain the assiciated haps. A child hap transaction table created for each product used.

                  RE: db structure help

                  Instead of child records for each HAPS, write one record for each HAPS of each product to create a flat file. In your example, I would write out three records, with the fields of product num., prod desc, HAPS name, CAS and Percent. Then your report would group on product num, and the monthly totals could be used in another report.

                    RE: db structure help


                    If you create a new child table to hold all the individual VOC and HAP quantities for your product definitions, the total list of pollutants will be there. This would be a new table with a one to many link from Products. For your needed report build a set that makes the HAP/VOC table the parent, link the Transaction and other tables to it and print them out in order by query and filtered for your date range. Report done.

                    The above conversion would be a fairly typical data normalization procedure. I would also suggest adding start dates and ending dates to the HAP/VOC table so you could change your product formulations and have the historical totals remain accurate. Adding an end date to a HAP record would remove it from the product formulation. If the state or Feds add new HAPs, that's and easy change, just add them to the product listings they are in and they automatically appear on the reports.

                    You could also run a Summarize operation to create a summary table with all the pollutant releases totaled for the month from this.

                    Does this sound like what you need?

                      What is a "Summarize operation to create a summary ta...."?

                      Is this feature available in a5v5?

                      I tried to lookeit up in the manual and I did not see anything.

                      I am looking for a5 to do the same as a pivot table in spreadsheet. (Maybe I off limits.)

                      Thanks a miilion,
