Quick tip: How to find your security identifier(SID) on your system?

-
Whenever we restore our Dynamics AX database, we have to update the UserInfo table to set the correct NetworkDomain, NetworkAlias and the SID fields.

Most of us have a simple SQL script which we run whenever we need this.

You may know the network domain and alias values but finding the SID value can be difficult. Well, the SID value or Security IDentifier value is a unique ID by which your system is identifier by other systems or network domains.

This value is stored in the registry.

Open the Windows registry by typing regedit in the run menu and navigate your way to HKEY_CURRENT_USER\Software\Microsoft\Protected Storage System Provider\S-X-X-XX-XXXXXXXXX- XXXXXXXXXX- XXXXXXXXXX-XXX

This is where you can find the SID of your system.

Hope this helps.

How to add empty ranges in query

-
In Dynamics AX programming, a common mistake I have seen when it comes to query ranges is passing an empty string value to the range. The developer here is expecting it to show all the records where the range field is empty. Instead, what we get is all records without the range being applied. As baffling as it may seems, it is easily explainable. The query engine in Dynamics AX, will not add a range if you don’t specify a value or if you specify an empty string because an empty string is treated as no value. So the following code will result in this SQL statement, query = new Query(); qbds = query.addDataSource(tableNum(ProjTable)); qbr = qbds.addRange(fieldNum(ProjTable, Name)); qbr.value(''); Select first fast * from ProjTable; But what was expected was something like, Select first fast * from ProjTable where Name == ''; So to work around this issue, use the SysQuery::valueEmptyString() static method which parses the empty strings correctly so that it

Get selected records in Dynamics AX 2012

In my earlier post, we discussed how we can retrieve all selected records on a list page. You can read that post here . Retrieving all selected records from a caller form is very easy. The code for this can be found in a number of places in standard Dynamics AX codebase. The general approach is to use the dataSource.getFirst(1) statement to get the first selected record and loop through the remaining using dataSource.getNext() . In Dynamics AX 2009, a new class was introduced for this purpose. This was the MultiSelectionHelper class. In Dynamics AX 2012, another new class has been introduced to retrieve the selected records. This is the MultiSelectionContext class. The MultiSelectionHelper class is an application class. It presents two constrcutors. The standard constructor method just creates a new instance of the MultiSelectionHelper class. When this construct is used, you will have to explicitly set the dataSource to be used for fethcing selected records. This can be done

The field with ID '0' does not exist in table - Cause and resolution.

Hello readers, In Dynamics AX coding, you should have come across this error sometime - The field with ID '0' does not exist in table 'SomeTable' So what causes this error and what is the possible resolution to it? Well, the most likely cause for this error is a missing mapping in a table map. Let us look at an example. I've a simple Map named CustVendAccount with one Account field. I've created two mappings - one with CustTable's AccountNum field and for the otehr mapping, I just specify VendTable but no field. This is how my map looks like, Now, I've a simple job which just passes either CustTable or VendTable as an argument and then we print the Account field in the map. static void CustVendAccountMap(Args _args) { CustTable custTable; VendTable vendTable; void readMap(CustVendAccount _custVendAccount) { info(strFmt("Value from table %1 is %2",tableId2name(_custVendAccount.TableId), _custV
