Dynamics AX Blog - Axapta 2.5

Find below a short example, how to add object nodes to a shared project through code.

The so modified Project will look like this:

The SELECT-Statement in the example lists only active BOM items (Table BOM) on (active using the fields FromDate and ToDate). If the second parameter of the macro is empty (zero date ()), so all BOM items are listed.

static void useMacroInSelectStatement(Args _args)
{
    bom bom;
    date emptyDate;
    
    // parameters: %1 = table instance, %2 date, %3 empty date value
    #localmacro.bomDateFilter
        && ( %2 == dateNull() || (
            ((%1.FromDate <= %2) && (%1.ToDate >= %2)) ||
            ((%1.FromDate == %3) && (%1.ToDate == %3)) ||
            ((%1.FromDate <= %2) && (%1.ToDate == %3)) ||
            ((%1.FromDate == %3) && (%1.ToDate >= %2))
            ))
    #endMacro
    ;
    
    while select bom
    where bom.ItemId == '123'
    #bomDateFilter(bom, systemDateGet(), emptyDate)
    {
        info(bom.bomid);
    }
}

I was asked this question recently and was not able to answer.

But i still knew that i had seen a page where this is explained in detail. But i knew neither find it manually nor using various search engines.

But in old documents of mine i found the source then, the trick to find it using search engines, is using the old name of Microsoft Dynamics AX - Axapta to look for it!

Do this, you will quickly find following page:

The following code is an example of how to build a query range based on a Form Data Source, which displays only "daily" records.

In the example the form-dataSource is named DataSourceName and it contains two date fields called FromDate and ToDate. Depending on a check box only records should be displayed, which that are valid for todays date.

The above method can be called for example in the executeQuery() of the DataSource.

The following method contains some snippets that can be used to call various functions/methods of the calling object (form).

If you change element.args() to e.g. _args and pass the arguments to the method, you can use the code within a class as well.

void workWithCallingRecord()
{
    common          common;
    object          object;
    formDataSource  formDataSource;
    formRun         formRun;
    inventDim       inventDim;
    salesTable      salesTable;
    int             i;
    ;
    // Call method from calling record
    if( element.args() &&
        element.args().record() )
    {
        common = element.args().record();
        if(common.isFormDataSource())
        {
            info(tableId2Name(common.TableId));
            if(formDataSourceHasMethod(common.dataSource(), identifierStr("someMethod")))
            {
                object = common.dataSource();
                object.someMethod();
            }
        }
    }
 

    // Call method from calling form
    if(element.args() && element.args().caller() && element.args().caller().handle() == className2Id('formRun'))
    {
        formRun = element.args().caller();
        if(sysFormRun::hasMethod(formRun, identifierStr("someFormMethod")))
        {
            object = formRun;
            object.someFormMethod();
        }
    }

    // Get value from calling record
    if( element.args() &&
        element.args().record() )
    {
        common = element.args().record();
        if(common.TableId == tableNum(salesTable))
        {
            info(common.(fieldNum(salesTable, salesId)));
        }
    }

    // Get value from calling datasource (form with multiple datasources)
    if(element.args() && element.args().caller() && element.args().caller().handle() == className2Id('formRun'))
    {
        formRun = element.args().caller();
        for (i = 0; i <= formRun.dataSourceCount(); i++)
        {
            formDataSource = formRun.datasource(i);
            if (formDataSource && formDataSource.table() == tablenum(inventDim))    // Search for specific table
            {
                inventDim = formDataSource.cursor();
                break;
            }
        }
        if(inventDim)
        {
            info(inventDim.InventLocationId);
        }
    }

    // Change data in calling datasource
    if(element.args() && element.args().caller() && element.args().caller().handle() == className2Id('formRun'))
    {
        formRun = element.args().caller();
        for (i = 0; i <= formRun.dataSourceCount(); i++)
        {
            formDataSource = formRun.datasource(i);
            if (formDataSource && formDataSource.table() == tablenum(salesTable))    // Search for specific table
            {
                salesTable = formDataSource.cursor();
                break;
            }
        }
        if(salesTable)
        {
            // Update data
            salesTable.PurchOrderFormNum = "Some value";
            salesTable.update();
        }
    }

    // Refresh calling datasource
    if( element.args() &&
        element.args().record() )
    {
        common = element.args().record();
        if(common.isFormDataSource())
        {
            formDataSource = common.dataSource();
            formDataSource.research(true);
        }
    }
}

If you try to change the AllowDuplicates-Property of a table index from No to Yes, the following error message may occur:

Illegal property value

In this case, presumably, the affected index is registered as PrimaryIndex or ClusteredIndex of the table.
