I am having problems withing with the Transfer SQL Server Objects task in SSIS. I would like to set the TablesList Property of the task to the value of an expression. At a high level, I need to transfer a table from one server to another but the table name is dynamic so I can't use a data flow task. Each iteration of the package execution will work off of one table so I need to set the TablesList property to the one table.
Since the property is a collection, I am getting errors when I attempt to just assign the TablesList property to the variable value in the expression builder. I get this error:
Error at Copy Table To Production: The result of the expression "@[User::TablesList]" on property "TablesList" cannot be written to the property. The expression was evaluated, but cannot be set on the property.
I also tried to open up the SSIS package in textpad and look at the formatting of the TablesList property and then set the variable to match what I saw in the XML......this gave me the same error.
Any suggestions on how to set a StringCollections property in SSIS?
Thanks in advance,
John

What you are trying to do is not straightforward, as you have found.
One way is described here, under Self Modifying Packages in SSIS?:

Thanks Phil. I had read through that article as well, but I was hoping there was an easier way to do it through the expression builder.
I had also sent an e-mail off to Jamie Thomson from SSIS Junkies and the reply that he sent states that you cannot set a collection property through an expression.
So it appears that the only way to do this is to use a script task.
Thanks.
