AX 2012 Financial dimension update

Here are 2 ways to update a financial dimension, while keeping the other dims. The result should be the same, just use whatever you prefer

To use those two method proceed like so:

  purchTable = purchTable::find('PURCHID', true);  
  purchTable.DefaultDimension = getNewDefaultDimension(purchTable.DefaultDimension, "COSTCENTER", "YOURVALUE");  
  purchTable.update();  

METHOD NUMBER 1:

 static RecId getNewDefaultDimension(RecId defaultDimension, Name dimName, str 255 dimValue)  
 {  
   DimensionAttributeValueSetStorage  dimStorage;  
   Counter               i;  
   DimensionAttribute         dimAttributeCostCenter;  
   DimensionAttributeValue       dimAttributeValue;  
   dimStorage = DimensionAttributeValueSetStorage::find(defaultDimension);  
   dimAttributeCostCenter = DimensionAttribute::findByName(dimName);  
   if(dimValue)  
   {  
     dimAttributeValue = DimensionAttributeValue::findByDimensionAttributeAndValue(dimAttributeCostCenter, dimValue, true, true);  
     dimStorage.addItem(dimAttributeValue);  
   }  
   else  
     dimStorage.removeDimensionAttribute(DimensionAttribute::findByName(dimName).RecId);  
   return dimStorage.save();  
 }  

METHOD NUMBER 2:

 static RecId getNewDefaultDimension(RecId defaultDimension, Name dimName, str 255 dimValue)  
 {  
   container c;  
   RecId   newdefaultDimension;  
   int    i;  
   c = AxdDimensionUtil::getDimensionAttributeValueSetValue(defaultDimension);  
   i = conFind(c, dimName);      
   if(!i && !dimValue)  
     return defaultDimension;  
   if(i)  
   {      
     c = conDel(c, i+1, 1);   
     c = conDel(c, i, 1);    
   }  
   if(dimValue)  
   {  
     c += dimName;  
     c += dimValue;  
   }  
   c = conDel(c, 1, 1);  
   c = conIns(c, 1, conLen(c) / 2);  
   newdefaultDimension = AxdDimensionUtil::getDimensionAttributeValueSetId(c);  
   return newdefaultDimension;  
 }  

To get the current value of a financial dimension:

 static str 255 getDimensionValue(RecId defaultDimension, Name dimName)  
 {  
   DimensionAttributeValueSetStorage  dimStorage;  
   Counter               i;  
   DimensionAttribute         dimAttributeCostCenter;  
   DimensionAttributeValue       dimAttributeValue;  
    dimStorage = DimensionAttributeValueSetStorage::find(defaultDimension);  
   return dimStorage.getDisplayValueByDimensionAttribute(DimensionAttribute::findByName(dimName).RecId);  
 }
