Calling method at runtime

In Dynamics AX, you can decide at runtime whether you need to call a method or not. See example below in which the find method of CustTable is called at runtime.

static void invokeMethodOnRunTime(Args _args)
{
   DictTable dictTable = new DictTable(tablenum(CustTable));
   CustTable custTable;
   //Check if class/table has method

   if(tableHasStaticMethod(dictTable, identifierstr('find')))
  {
       custTable = dictTable.callStatic(tableStaticMethodStr(CustTable, Find), '4000');
       info(custTable.name());
  }

}

Getting number of rows loaded

To get the number of rows loaded to the Dynamics AX datasource, you can use the following function of the datasource.

[datasource].numberOfRowsLoaded();

For example:

custTable_ds.numberOfRowsLoaded();

Modify label of Runbase OK button

There are number of requirements when a developer wants to change the label of runbase dialog OK button in Dynamics AX. You can use the following code to change the label of OK button on Runbase dialog in AX

Insert the following code after the super() call in the putToDialog method

protected void putToDialog()
{
FormBuildCommandButtonControl commandButton;
;
super();
commandButton = dialog.dialogForm().control("OkButton");

commandButton.text("Yes");

}

Multi Tab Lookups in AX

Lets say you  have a requirement in which you want to show multiple tabs on a lookup form. For example,  you have a field in which you want your user to either select a customer or vendor from a lookup then this could be the best option to show multiple tabs and let user select either customer or vendor.

Following are the steps to get this done.

* Create a new form "LookupForm" with multiple tabs on it.
* The FormHelp property of the EDT should be set to the form you just created "LookupForm".
Its all done!!! this is how lookup will look like

Multi tab lookup

Finding AOT object by its propery

In Dynamics AX we can find all the AOT objects by specifying some property. Lets say we want to find all the tables in AOT having "SaveDataPerCompany" property set to No.

We can use the following x++ job

The X++ job below shows how to find all tables in the AOT where the SaveDataPerCompany property is set to No.
static void se_findAOTObjectByProperty(Args _args)
{
#AOT
TreeNode treeNodeTables = TreeNode::findNode(#TablesPath);
TreeNode treeNode;
str strPropertyName = 'SaveDataPerCompany';
str strPropertyValue = 'No';
;

// first table
treeNode = treeNodeTables.AOTfirstChild();
while (treeNode != null)
{
if (treeNode.AOTgetProperty(strPropertyName)== strPropertyValue)
{
info(treeNode.AOTname());
}
// next table
treeNode = treeNode.AOTnextSibling();
}
}

Conditional Joins in x++

In this post, we will try to learn how we can apply conditional joins in x++ to cater the complex scenarios in the development of Microsoft Dynamics AX.

Conditional joins in Dynamics AX (x++)
Here is the code to apply joins conditionally in Microsoft Dynamics AX.
query = new Query();
dsInventTable = query.addDataSource(tableNum(InventTable), "InventTable");
dsInventItemBarCode = dsInventTable.addDataSource(tableNum(InventItemBarCode), "InventItemBarCode");
dsInventItemBarCode.joinMode(JoinMode::ExistsJoin);

// Add our two ranges
queryBuildRange1 = dsInventTable.addRange(fieldNum(InventTable, DataAreaId));
queryBuildRange2 = dsInventItemBarCode.addRange(fieldNum(InventItemBarCode, DataAreaId));
 


No we can play with our query  
Find all records where either the ItemType is Service, or the ItemType is Item and a barcode exists. The join criteria is only applied in the second half of the expression, so all Service items will appear irrespective of whether they have a bar code. Again, this is not possible to achieve using the standard query ranges.

queryBuildRange2.value(strFmt('((%1.%2 == %3) || ((%1.%2 == %4) && (%1.%5 == %6)))',
query.dataSourceTable(tableNum(InventTable)).name(), // InventTable %1
fieldStr(InventTable, ItemType), // ItemType %2
any2int(ItemType::Service), // %3
any2int(ItemType::Item), // %4
fieldStr(InventTable, ItemId), // ItemId %5
fieldStr(InventItemBarCode, ItemId))); // %6

Complex Query Ranges in Dynamics AX

In this article, we will learn how to apply simple and complex ranges in Dynamics AX queries.

We will play with a query having a single datasource in it. Following is the code for adding a query with a datasource.

query = new Query();
dsInventTable = query.addDataSource(tableNum(InventTable));
// Add our range
queryBuildRange = dsInventTable.addRange(fieldNum(InventTable, DataAreaId));
 
Simple criteria

Lets find the record where the value of ItemId field is B-R14. Take note of the single quotes and parenthesis surrounding the entire expression.
queryBuildRange.value(strFmt('(ItemId == "%1")', queryValue("B-R14")));

Find records where the ItemType is Service. Note the use of any2int().
queryBuildRange.value(strFmt('(ItemType == %1)', any2int(ItemType::Service)));
 
Find records where the ItemType is Service or the ItemId is B-R14. Note the nesting of the parenthesis in this example.
queryBuildRange.value(strFmt('((ItemType == %1) || (ItemId == "%2"))', any2int(ItemType::Service), queryValue("B-R14")));
 
Find records where the modified date is after 1st January 2000. Note the use of Date2StrXpp() to format the date correctly.
queryBuildRange.value(strFmt('(ModifiedDate > %1)', Date2StrXpp(01012000)));

Complex criteria with combined AND and OR clauses
We need to find those records where the ItemType is Service, or both the ItemType is Item and the ProjCategoryId is Spares. This is not possible to achieve using the standard range syntax.
Note also that in this example, we are using the fieldStr() method to specify our actual field names and again, that we have nested our parenthesis for each sub-expression.

queryBuildRange.value(strFmt('((%1 == %2) || ((%1 == %3) && (%4 == "%5")))',
fieldStr(InventTable, ItemType),
any2int(ItemType::Service),
any2int(ItemType::Item),
fieldStr(InventTable, ProjCategoryId),
queryValue("Spares")));

Extended Query Range in Dynamics AX

Many developers often stuck while they try to apply range to the dynamics ax query to filter records based on some conditions. We will try to explore the query ranges in this article and will try to play with some examples to learn how we can apply query ranges using x++ to the Dynamics AX queries.

Let's say we want to apply "OR" range on a SAME field then we have 2 ways to do it.

Method 1:


Query q;
QueryBuildDataSource qbd;
QueryBuildRange qbr;
q = new Query();
qbd = q.addDataSource(TableNum(CustTable));
qbr = qbd.addRange(FieldNum(CustTable, AccountNum));
qbr.value('4005, 4006');

The above x++ code will generate following SQL statement.
"SELECT * FROM CustTable WHERE ((AccountNum = N'4005' OR AccountNum = N'4006'))"

Method 1:

qbr.value(strFmt('((AccountNum == "%1")
(AccountNum == "%2"))',
QueryValue('4005'),
QueryValue('4006')));

The above x++ code will generate following SQL statement.
"SELECT * FROM CustTable WHERE ((((AccountNum == "4005") || (AccountNum == "4006"))))"

Let's say we want to apply "OR" range on a DIFFERENT fields


You can use the following x++ code to apply the OR range to the different fields

qbr = qbd.addRange(FieldNum(CustTable, DataAreaId));
qbr.value(strFmt('((%1 == "4000")
(%2 == "The Bulb"))',
fieldStr(CustTable, AccountNum),
fieldStr(CustTable, Name)));

The above code will generate following sql statement
"SELECT * FROM CustTable WHERE ((((AccountNum == "4000") || (Name == "The Bulb"))))"

Note: We have used DataAreaId field above to apply the range however, the actual range is on AccountName and AccountNum field. This means when you use range value expressions you can use any field to obtain range object and use it to insert your range in the query. Using DataAreaId field for this purpose is the best practice.

Welcome

Welcome to the Dynamics AX blog.

Here we are going to discuss Dynamics AX functional and technical issue and I will be sharing some tips and tricks that we use during the development of Dynamics Ax projects.
The main goal is to learn the tips and tricks and to provide the help on the topics that are not available on google right now.
