I've got an SSIS package that loads data from a flat file source into a table within a SQL Server Database i then have a SQL task to get specific data and load into an excel destination, i want to add another SQL task to load different data into the same excel workbook but on a different tab is this possible?
Yes it's possible. You can use same excel file to save diffrent data sets in different worksheets. In Excel destination editor for Excel Destination component press [New] button and change name of the table in CREATE TABLE statment to name of the worksheet you want to use. After that select new it as a worksheet name.
