Harness the power of PowerShell and the Business Connector too.

Hi Everyone. My name is Jason Larson. I am a Premier Field Engineer with the Dynamics AX team in the central region. I was recently asked how we could compare data in a text file outside of AX with data in AX.

The business scenario for the customer was to compare financial dimensions between ERP systems but in this example I am comparing users in the userinfo table with a list of users in a text file.

 I thought of a few ways to do this:

1) Import the external file into an intermediate custom table in the AX database and use T-SQL to compare.

2) Import the external file using DIXF(DMF) and perform the compare using x++.

3) Using the business connector and connect into AX using PowerShell and perform the compare in a PowerShell Script by pulling the AX data out.

I thought option 3 was interesting. Using the BC and PowerShell seemed like a logical fit to me. Here is what I came up with:

File on the filesystem is c:\userlist.txt

This is what the file contains:





The table in AX I am comparing against in this example is the userinfo table. The table contains this:





 #Here is the script.

#Read in the userlist file and create an arraylist without a fixed size.

$userlist = Get-Content c:\userlist.txt
$array = New-Object System.Collections.ArrayList

Add-Type -Path "C:\Program Files\Microsoft Dynamics AX\60\BusinessConnector\Bin\Microsoft.Dynamics.BusinessConnectorNet.dll"
$ax = new-object Microsoft.Dynamics.BusinessConnectorNet.Axapta
$b = $ax.CreateAxaptaRecord("userinfo")
$b.ExecuteStmt("select id from %1")
    $array.add($b.get_field("id")) | out-null
    $ | out-null

$a = "<style>"
$a = $a + "BODY{background-color:AliceBlue;}"
$a = $a + "TABLE{border-width: 1px;border-style: solid;border-color: black;border-collapse: collapse;}"
$a = $a + "TH{border-width: 1px;padding: 0px;border-style: solid;border-color: black;}"
$a = $a + "TD{border-width: 1px;padding: 0px;border-style: solid;border-color: black;}"
$a = $a + "</style>"

compare-Object $userlist $array | Sort { $_.InputObject.diff } | convertto-html -head $a -body "<H2><= is found in external file. => Is only found in AX. </H2>" | out-file "c:\out.html"

The results:


The script above will match on different case. To change that behavior use -caseSensitive like so on the compare-object line

Compare-Object $userlist $array -caseSensitive | Sort {$_.InputObject.diff } | convertto-html -head $a -body "<H2><= is found in external file. => Is only found in AX. </H2>" | out-file "c:\out.html"

    Very Helpful Jasonlar.  The tie in technique that you demonstrated here has a lot of use cases.  I never thought of using the Business Connector in my powershell scripts until now but this is definitely good to know — particularly with the scheduling enhancements within powershell and with integrations.

    One of the thoughts was to automate the process to run on some schedule using Windows Task Scheduler. Then email the results using the send-mailmessage cmdlet.

    Why you just  didn't copy data in Excel and compare them using VLOOKUP function?
