Financial Dimensions on SSRS Reports

Hi Guys,

I have created a report which is related to Purchase orders where I need to display the financial dimensions from the PO lines. I am using below code for that and it works fine with Department & Cost center I need to add dimension Machine also in the report but it doesn't work. what could be the reason ?  

below I used to get the cost center:-

void Costcenter(DimensionDefault _defaultDimension)
{
DimensionAttributeValueSet dimensionAttributeValueSet;
DimensionAttributeValueSetItem dimensionAttributeValueSetItem;
DimensionAttribute dimensionAttribute;
DimensionAttributeValue DimensionAttributeValue;
DimensionFinancialTag dimensionFinancialTag;

;

select Value,Description from dimensionFinancialTag
join dimensionAttributeValue where dimensionFinancialTag.RecId == dimensionAttributeValue.EntityInstance
join dimensionAttribute where dimensionAttributeValue.DimensionAttribute == dimensionAttribute.RecId
join dimensionAttributeValueSetItem where dimensionAttributeValue.RecId == dimensionAttributeValueSetItem.DimensionAttributeValue
&& dimensionAttributeValueSetItem.DimensionAttributeValueSet == _defaultDimension
&& DimensionAttribute.Name == 'Center';

Costcenter = dimensionFinancialTag.Value;

}

below for Machine which doesn't work. 

void Machine(DimensionDefault _defaultDimension)
{

DimensionAttributeValueSet dimensionAttributeValueSet;
DimensionAttributeValueSetItem dimensionAttributeValueSetItem;
DimensionAttribute dimensionAttribute;
DimensionAttributeValue DimensionAttributeValue;
DimensionFinancialTag dimensionFinancialTag;

;

select Value,Description from dimensionFinancialTag
join dimensionAttributeValue where dimensionFinancialTag.RecId == dimensionAttributeValue.EntityInstance
join dimensionAttribute where dimensionAttributeValue.DimensionAttribute == dimensionAttribute.RecId
join dimensionAttributeValueSetItem where dimensionAttributeValue.RecId == dimensionAttributeValueSetItem.DimensionAttributeValue
&& dimensionAttributeValueSetItem.DimensionAttributeValueSet == _defaultDimension
&& DimensionAttribute.Name == 'Machines';

Machine = dimensionFinancialTag.Value;

}
