  Hi,

  Today I'm facing a very complicated challenge , I have a connection trough PowerPivot to an Excel file and I'm trying to concatenate the rows into one single column , here is how my data looks :

  Sales Order Identifier..........Billing Document Identifier................Billing Document Calendar Date

  75210241...............................859889179......................................5/9/2013

  75210241...............................9647889180....................................5/11/2013

  81106197...............................9653785136...................................5/12/2013

  The code for the above is this one :

  SELECT DISTINCT ['Direct_VPA invoice numbers$'].[Sales Order Identifier],['Direct_VPA invoice numbers$'].[Billing Document Identifier],

  ['Direct_VPA invoice numbers$'].[Billing Document Calendar Date]

  FROM ['Direct_VPA invoice numbers$']

  Basically an SO might contain different Billing Documents , if that's the case ,I'll need to concatenate that SO into one single row

  I'm trying to change my data to look like this:

  Sales Order Identifier...........Billing Document Identifier..............Billing Document Calendar Date

  75210241......................... 859889179 , 9647889180..................5/9/2013, 5/11/2013

  81106197................................9653785136...................................5/12/2013

  So far I've tried some variations of the next code but I keep getting an error :

  SELECT DISTINCT

  ['Direct_VPA invoice numbers$'].[Sales Order Identifier]

  , STUFF((

  SELECT N', ' + CAST(['Direct_VPA invoice numbers$'].[Billing Document Identifier] AS VARCHAR(255))

  FROM ['Direct_VPA invoice numbers$'] f2

  WHERE f1.['Direct_VPA invoice numbers$'].[Sales Order Identifier] = f2.['Direct_VPA invoice numbers$'].[Sales Order Identifier]

  FOR XML PATH (''), TYPE), 1, 2, '') AS FileNameString

  FROM ['Direct_VPA invoice numbers$'] f1

  Error "IErrorInfo.GetDescription failed with E_FAIL(0x80004005)."

  Any light here would be much appreciated

  Please see the following article for one pretty easy method.

  RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
  First step towards the paradigm shift of writing Set Based code:
  ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

  Change is inevitable... Change for the better is not.
