Custom Lookup for Dimensions in AX 2012 – For User Defined Dimensions

 

In this article, giving an example for defining the lookup for dimensions in simple way.
This example will cover only for user Defined dimensions.

For this
1)      Created a form and added two string controls.
2)      Named as
Control: Name: Dimensionlist, Auto declaration – Yes
Control: Name: DimValues
3)      Override the lookup method for Dimensionlist

public void lookup()
{
Query           query;
SysTableLookup  sysTableLookup;
super();
sysTableLookup = SysTableLookup::newParameters(tableNum(DimensionAttribute), this);
sysTableLookup.addLookupfield(fieldNum(DimensionAttribute, Name));
query = new Query();
query.addDataSource(tableNum(DimensionAttribute)).
addRange(fieldNum(DimensionAttribute, Type)).
value(queryValue(DimensionAttributeType::CustomList));
sysTableLookup.parmQuery(query);
sysTableLookup.performFormLookup();
}

4)      Override the lookup method for DimValues

public void lookup()
{
DimensionAttribute                  dimensionAttribute;
DimensionAttributeDirCategory       dimAttributeDirCategory;
Query                               query = new Query();
SysTableLookup                      sysTableLookup;
dimensionAttribute = DimensionAttribute::findByName(Dimensionlist.text());
super();
// Only user defined dimensions will have a financial tag category
if (dimensionAttribute.Type == DimensionAttributeType::CustomList)
{
select firstonly DirCategory from dimAttributeDirCategory where dimAttributeDirCategory.DimensionAttribute == dimensionAttribute.RecId;
sysTableLookup = SysTableLookup::newParameters(tableNum(DimensionFinancialTag), this);
// Add name field to be shown in the lookup form.
sysTableLookup.addLookupfield(fieldNum(DimensionFinancialTag, Value));
sysTableLookup.addLookupfield(fieldNum(DimensionFinancialTag, Description));
query = new Query();
query.addDataSource(tableNum(DimensionFinancialTag)).
addRange(fieldNum(DimensionFinancialTag, FinancialTagCategory)).
value(queryValue(dimAttributeDirCategory.DirCategory));
sysTableLookup.parmQuery(query);
// Perform the lookup.
sysTableLookup.performFormLookup();
}
}

Run:


We can use the same concepts for Dimension controls on Ax 2012 SSRS reports dialog. To build the report dialog UI with dimension controls.
