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.

    Filtering on Calculated Field?

    I'm trying to filter a browse based on a calculated value. Specifically, I'm trying to get a list of "past due" accounts. The filter I'm trying to use is:

    (INT(AgeMonths(open_items->First_Pmt_Date,date())+1)*open_items->Pmt_Amt)>total(Journal_Entries->Amt_Credited,GRP->open_items,GRP->journal_entries)

    In short, it calculates the number of months due, to date, times the payment amount... and compares that to the number payments that are related to the open item.

    The filter works... that is, when I'm in the filter definition window all looks good, it calcs correctly, shows "true" or "false" correctly, etc.

    BUT, when I run the browse... A5 reports that I "can't use function in this context."

    So, how should I be going about this... i.e. how do I get a list of past due accounts?

    Thanks, in advance, for any help.

    Hi Michael:
    I think the problem is with the Total() function, I had same problem. When filtering, A5 just won't take Total(), Maximum(), etc... probably because these a report functions. Try with a DBsum() or Tablesum() and see how it goes.

      Thanks Gaby...

      I tried tablesum... runs "for...ever," then returns very weird results. The performance problem is likely the lack of an appropriate index... but the results look suspect.

      Haven't tried dbsum yet, but I will.

        This what the help file says about Total():

        This function is typically used in Reports to total records in a group, or in Forms to total records in a one-to-many child table.

        As Gaby says, I would definitely not use it in a filter.

          Michael, maybe if you describe the table & field structures we could suggest some alternatives. Without narrative explanations telling us what things are and where they're to be found in relation to each other it's difficult to tell if you're aging invoices separately, or if you're aging open accounts for each customer, for example.
