Get Product Attribute Values in AX 2012 - Let's Code!

Hi There,

I hope that your weekend went OK and that you are ready for another interesting article about AX 2012.

Today I wanted to talk a bit about Product Attributes in AX 2012. As we all know by now, with the introduction of AX 2012 things got a little bit more complicated when dealing with Product Categories and Attributes. 

Categories in AX2012 are used to classify products, customers, and other type of data for reporting and analysis. In addition, each category must have a parent , and child elements (you can learn more about it here).

On the other hand, Product Attributes in AX 2012 focus on the details that we want to maintain for certain products. Before you can create a product attribute, you must define an Attribute Type. Now the great thing about product attributes is that we can assign them from different modules of AX 2012, and the attribute will belong to that module only and not other (you can learn more about it here).

When trying to get a Product Attribute Value for a Product in AX 2012, it is important to understand that there are three main tables involved.

 EcoResProductAttributeValue
 EcoResAttribute
 EcoResValue 

The following code will help you get the Product Attribute Value:

public static AttributeValueText getItemIdAttributeValue(RefRecId _product)
{
    EcoResProductAttributeValue ecoResProductAttributeValue;
    AttributeValueText          attributeValueText;
    InventTable                 InventTable;
    EcoResAttribute             ecoResAttribute;
    EcoResValue                 ecoResValue;
    ;


    //We only query a level down the inventtable and just used the InventTable.Product RecId as a reference for ecoResProductAtributeValue

    while select ecoResProductAttributeValue
        where ecoResProductAttributeValue.Product == _product
            join Name from ecoResAttribute
            where ecoResProductAttributeValue.Attribute ==    ecoResAttribute.RecId
                join ecoResValue where ecoResValue.RecId == ecoResProductAttributeValue.Value
    {
        attributeValueText = ecoResValue.value();
    }

    return attributeValueText;
}

If you notice, the only parameter we need in the example above is the Inventory Table Product Reference in order to find the correct value within the
EcoResProductAttributeValue View. 

The alternative can be to use the Inventory Table in the query as well, and it will look like this:


public AttributeValueText getItemIdAttributeValue()
{
   
    EcoResProductAttributeValue ecoResProductAttributeValue;
    AttributeValueText          attributeValueText;
    InventTable                 InventTable;
    EcoResAttribute             ecoResAttribute;
    EcoResValue                 ecoResValue;
    ;

    while select InventTable where InventTable.itemid == this.parmItemId()
        join RecId from ecoResProductAttributeValue
        where ecoResProductAttributeValue.Product == InventTable.Product
            join Name from ecoResAttribute
            where ecoResProductAttributeValue.Attribute == ecoResAttribute.RecId
                join ecoResValue
                where ecoResValue.RecId == ecoResProductAttributeValue.Value
    {
        attributeValueText = ecoResValue.value();
    }

    return attributeValueText;

}

In the code above I'm using an Inventory Table Item Id and referring the selected record in the EcoResProductAttributeValue View. 


Until the next post and have a great week.
