SSIS Converting Flat File with Header and Detail lines

Hi,

I have a flat file that has two row types (OH = Order header, OL = Order line). One OH row can have multiple OL lines. I would like to combine the OH data rows and the OL data rows into one output row.

So for example the source data may look like this:

OH, Ted, #12345, M, United Kingdom
OL, 1, 2, 3, 4
OL, 2, 2, 4, 5
OH, Bob, #12346, M, United Kingdom
OL, 2, 4, 4, 6
OL, 2, 2, 4, 7

I would like the target file to be:
Ted, #12345, M, United Kingdom, 1, 2, 3, 4
Ted, #12345, M, United Kingdom, 2, 2, 4, 5
Bob, #12346, M, United Kingdom, 2, 4, 4, 6
Bob, #12346, M, United Kingdom, 2, 2, 4, 7

I know I could split the data rows into two outputs but I do not know how I would then link the data back together as there is no link in the source file between the OH and OL rows.

Thanks, Greg
