Create dynamic filename in SSIS

Hi,

I'm migrating a DTS package to SSIS. In the DTS, I have an ActiveX Script that set a variable (filename with date and time as the file extension) and a Dynamic Properties Task that set the filename to a Text-File destination feeded by a Transform Data Task that uses a SQL query that extract and format the data to the required field-length. That works fine.

Now, I need to do the same in SSIS. Flat-File Connection Manager ask for an existing file. But this file is created by the DTS, it doesn't exist yet. And anyway, filename should be dynamic.

I tried Raw File, where I can select a variable as filename, but the output is binary.

The result file is imported by a SAP ERP system, so it has to match the required fix field-length.

how can I do this in SSIS?

thanks for your time and help

You will be able to do the same thing with a csv destination. You will need to set the destination filename as either an expression or a variable. If variable you will be able to evaluate the variable as an expression.

how can I set the destination as a variable? When setting up a flat-file connection, it ask for a valid file name, I have to input something there. How can I use Expression to dynamically change filename of a flat-file connection ?

In the properties of the flat file connection manager you will see a section called expressions. In the expressions section set the Property to be updated to ConnectionString and enter your expression to build your filename.

Yuo will still have to enter a filename so it will validate but upon run-time this will be over-ridden.

ok good. I've set the property to my variable name. But don't know why, the variable never changes when I execute the ActiveX Script:

Function Main()
dim NomFic
      NomFic = year(now())  & Pad2Left(month(now()))  & Pad2Left(day(now())) & Pad2Left(hour(now())) & Pad2Left(minute(now()))
      DTSGlobalVariables("APicking").value = DTSGlobalVariables("Path").value + DTSGlobalVariables("APickingName").value + NomFic

      Main = DTSTaskExecResult_Success
End Function

Function Pad2Left(ByVal Value)
   Pad2Left = Right("0" & CStr(Value), 2)
End Function

I have set the ConnectionString Expression to the variable "APicking". The ActiveX is executed before the Data Flow Task. Variable is not ReadOnly. But it don't changes and I generate same filename everytime.

If you look at the properties of the variable and set EvaluateAsExpression you can actually set the value of the variable there. You shouldnt need to use a script task to do this.

ok sorry, I had a bug in my variable. File create with correct name and data is fed into it. Still have a problem with the formatting. All rows are inserted into a single line in the file. There is no CR/LF, although Row Delimiter is CR/LF and preview of data is looking good...

This is my extraction query:
SELECT  DISTINCT
RTRIM( dbo.PAD(a.[vpmOrder], 22, ' ', 'L')) AS PO,
      RTRIM(dbo.PAD(a.itmCode, 6, ' ', 'L')) AS ITEM,
      'V' as TYPE,
      RTRIM( dbo.PAD(a.[vpmNoColis], 20, ' ', 'L')) as COLIS,
      dbo.PAD(a.[itmQtyReelle], 6, '0', 'L') AS QTY,
      RTRIM( dbo.PAD(b.[orderDate], 8, ' ', 'L')) as DATE
FROM   TB_vpmPreColisage a
INNER JOIN  [TB_vpmOrder] b ON a.[vpmOrder] = b.[orderNO]
INNER JOIN [TB_vpmColis]  ON TB_vpmColis.[vpmNoColis] = a.[vpmNoColis]
WHERE [orderCompleted] IS NOT NULL AND b.[orderTreated] IS NULL

In Flat-File Connection Manager, I selected an existing valid file and delimited the width of each columns. Row Delimited is CR/LF. Output file gives:
              1007540 04235V         S075400221200003520101115                 1007540 09263V         C075400041200001520101115 ....
all the extracted data into a single row....And the preview looks good.

What I'm doing wrong?

ok found it. I had to select "Ragged Right" in the Format properties of the Flat-File Connection Manager to have the CR/LF add at the end of each row.

works like a charm now
