Calculation of a table summary field


Recommended Posts

I'm not sure how to explain this properly but I will try.

I have 2 tables, one main customer table and a phone log table with over 700,000 records.

They are related with a customer number field.

on my main customer table, I currently show the last phone log entry, date and user initials with a field in the main customer table called (last phone log name) (last phone log date) (last phone log initials) using the last function.

This works perfectly but it is massively slowing down when I scroll through hundreds of records on my main customer table.

Is there any way to create a new field or store this information so it isn't calculated on the fly, any thoughts?

I think if you just sort the relationship in descending order by date of the phone log entries, simply putting those fields on the Customer layout (or a 1 row portal) should do the trick.  Then you wouldn't need what's probably an unstored calc at all.

Steve's idea makes sense in form view. If you're talking about scrolling in list or table view, it's going to be slow either way. If you're using a script to create the phone log record it should be fairly easy to also store the most recent info in a field in the customer record.

      Hi,
      I have two table: Invoice and Customer.  I like to have the total of all the invoice for a customer between certain date in the Customer portal that show all the customers, but I got a error when I try to debug..
      ExecuteSQL("SELECT SUM(I.TotalAmount) FROM Invoice I JOIN Customer C ON I._kf_CustomerID = C.__kp_CustomerID WHERE date(I.InvoiceDate) between date(C.SearchFromDate ) and   date(C.SearchToDate )" ; "" ; "" )
      I have an error and couldn't figure it out.  Thanks...

      I have a client that has been using a send email script step  that brings up the outlook email client on the desktop.  This as worked for years no problem.  It has stopped work on 3 of 35 computers within the last two weeks.  I talked with there IT personal and they have assured me that no updates have happened.  The actual error is -
      Microsoft Office Outlook
      Either there is no default mail client or the current mail client cannot
      fulfill the messaging request.  Please run Microsoft Outlook and set it as
      the default mail client.
       
      I have double checked with system default  and Outlook's settings.  Both are set to default.
      The client is using the latest version of office 360's and the latest version of FileMaker 18 advance. Both 64bit.
      Any suggestions are welcome.

      I have an excel sheet that controls bills of ladings for a forestry company.  In the example you can see that there is lots going on with this Bill.  It has a payperiod, mill, truck that delivered it, etc.
      I would like setup a database to monitor this.  The fields CT1, CT2, Skid1, Skid2. PROC1, PROC2 are all contractor numbers.  There are 6 contactors.  The percentages in each line are the amount of the volume they performed  In the third line there is a value in CT1 only...they get 100% of the volume.  I can figure out most of this, but am stumped on how I can monitor when a contractor does multiple jobs..ie in line one, contractor 5, cuts and skids.  All 6 contractors could be involved in one BOL. Each one of these jobs, cutting, skidding and processing each has their own respective rate of pay as well.   I think i need a way to break down each line so that I can produce pay summaries for each of the contractors.  I had started this years ago, and thought I asked in a forum, but can't remember where.  Nonetheless, they stopped using multiple contractors per load...Now they have returned, so I am back at it.  So if this is a repost from years ago I apologize.  
      Thanks in Advance

      I am using Filemaker Server 18 on Windows Server 2012 R2
      Been using it for years with no issues
      Currently when I log in to the console it is very sluggish.
      When I get to the Dashboard it shows No databases, then it auto refreshes and the database list appears.
      Within 15 seconds of scrolling the database list to open files the screen refreshes. This situations is happening over and over in a loop.
      Any Thoughts on what is causing this issue?

      I get an error 3 when using a script to Export Records via WebDirect. Using FileMaker Server 18 and have tried both Safari and Chrome both with same results. I have tried using the temporary path, desktop path, and documents path. I have tried using with the automatically open and not. I have tried writing a tab delimited and comma delimited file. Does anyone have ideas I haven't yet tried?
