Conditional split with dependence?

I have setup a SSIS package that takes a flat file fixed width input, and stores it to two SQL server tables in the same database. The flat file contains two types of records, lets call them Type1 and Type2. The two types of records are formatted differently, and the first character determines what type the record is. I used a conditional split to send record type1 down one path, and type2 down the other. On each of those I use a derived column task to build all the fields and then store to the table with the OLE destination. I put any errors that occur (like truncation) into an error table by setting the "redirected row" feature vs "Fail Component". This all works well and I have no issues.

The dilema is as follows. Type1 is essentially a parent record and the Type2 record is a child. There is a shared primary key / foreign key relationship field. I want errors when processing type1 to cause the associated type2 to also be redirected to the error table vs being inserted.

If anyone has suggestions on how this could be done, reference articles, etc... please let me know.

Thanks.

Perhaps use a merge join on the error output of the Type1 flow together with the Type 2 data flow. Then use a conditional split to look for matches. If you have a match, you direct the Type 2 record (along with the Type1 record) down a separate error-handling flow. If you don't have a match, the Type2 records can be processed accordingly.|||

I'm trying your suggestion and I think it will work. But I am having an issue. I have my original flat file source, which I read into the SSIS package as just rows. So I do CRLF search to bring in as one column. I then send it to a derived column component after a conditional split to perform all the "substrings" to get the actual columns out of the data.

In order to do a merge join you must use sorted columns. I was able to set sorted column on the flat file data source and single column, which does me no good. I need to be able to set the sorted column on the derived columns after the data has been put into columns. Is there any way to set the sort column on a derived column? If I can do that it will solve my issues.

Thanks.
