Lineage ID Errors

I am running an SSIS package and I keep getting this error when it gets to a the dataflow task. I have a bit of an idea of what it means, but I can't figure out how to fix it. IF anybody could explain this error and fixes for it that would be of immense help. Thank you.

Error: 0xC004701C at Load Server Security, DTS.Pipeline: input column "Server" (1434) has lineage ID 1421 that was not previously used in the Data Flow task.
Error: 0xC004706B at Load Server Security, DTS.Pipeline: "component "OLE DB Destination 1" (1420)" failed validation and returned validation status "VS_NEEDSNEWMETADATA".
Error: 0xC004700C at Load Server Security, DTS.Pipeline: One or more component failed validation.
Error: 0xC0024107 at Load Server Security: There were errors during task validation.The first error simply says that you have a column in the data flow, Server, that isn't used.

The second error looks to me like there were database changes to that table and now the OLE DB destination needs to be updated. Double click on the OLE DB destination and select the mappings tab. If no changes need to be made, simply click OK.|||

Possible reason could be if your destination table structure or the column data type changed.

Limitations in term of number of tasks and number of columns

Hi,

I am currently designing a SSIS package to integrate data into a data warehouse fact table. This fact table has about 70 columns among which 17 are foreign keys for dimension tables.

To insert data in that table, I have to make several transformations and lookups. Given the fact that the lookups I have to make are a little complicated, I have about 70 tasks in my Data Flow.
I know it's a lot, but I can't find a way to make it simpler. It seems I really need all these tasks.
Now, the problem is that every new action I try to make on the package takes a lot of time. At design time, everything is very slow. My processor is eavily loaded each time I change a single setting in one of the tasks, and executing the package in debug mode takes for ages. If I take a look at the size of my package file on disk, it's more than 3MB.

Hence my question : Are there any limitations in terms of number of columns or number of tasks that can be processed within a Data Flow ?

If not, then do you have any idea why it's so slow ?

Thanks in advance for any answer.
Two things. One, the XML on your package has to be extremely large and cumbersome for the engine to work with. I would imagine this is one source of your slowness. If you can break your package up into smaller packages, that would be much better and likely easier to support.

Two, you might have some success in working offline via the "Work Offline" switch under the SSIS menu in BIDS. That is, perhaps some of the slowness is in validating your data flows against the connections.
