Stored procedure fails when run from SSIS DataFlow task

Question

I'hv a stored procedure (with dynamis SQL), taking colums names as parameters to run and returns dynamic columns in output. E.g. if I pass @ipselect = '*' it will returns all columns in output, when I pass @ipselect =  'column1, column2, column3'  
,it will returns 3 columns in output.
Now I have SSIS package. I've Data Flow task in foreach loop container and it is taking parameter from client table. e.g
clientid       column name
1                        *
2                columns1,columns2,column3
3               columns1,columns2,column3,columns4,columns5,column6
4                       *
Foreach container loop through each client id and set ipselect parameter with
column name  and that value is being passed to @ipselect stored procedure in Dataflow task. When there is @ipselect = '*' it runs fine ,returns all columns and write to destination. But when there is ipselect = 'columns1,columns2,column3',
it fails with below error:
[OLE DB Source [1]] Error: SSIS Error Code DTS_E_OLEDBERROR.  An OLE DB error has occurred. Error code: 0x80040E55.
An OLE DB record is available.  Source: "Microsoft SQL Server Native Client 10.0"  Hresult: 0x80040E55  Description: "Column does not exist.".
[SSIS.Pipeline] Error: SSIS Error Code DTS_E_PRIMEOUTPUTFAILED.  The PrimeOutput method on component "OLE DB Source" (1) returned error code 0xC0202009.  The component returned a failure code when the pipeline engine called PrimeOutput().
The meaning of the failure code is defined by the component, but the error is fatal and the pipeline stopped executing.  There may be error messages posted before this with more information about the failure.
Any suggestion or solution would be really helpful.
Thanks!!

Hi Kevin,
Just an addition. To create SSIS package programmatically, please refer to the document:

To implement dynamic column mapping through SSIS Script Component, please refer to:
