I have a package which uses a csv as input and I need to populate several columns (12) with data from the previous row when that data is missing. As I am inexperienced with SSIS and know nothing about C#, I figured it would be best to start with one column and apply that solution to the other columns. Very simply, when the column MRN is null, use the PrimaryInsuranceCompanyID from the previous row to populate PrimaryInsuranceCompnayIDout. Unfortunately, the script I have tried does not seem to be working as I expected it to as PrimaryInsuranceCompnayIDout has 0 in each row of the output flat file.
Is it possible to simply replace PrimaryInsuranceCompanyId? I received a message that it was Read-Only when I tried to do that.

{
string primins = "";
string PrimaryInsuranceCompanyIDout;
public override void Input0_ProcessInputRow(Input0Buffer Row)
{
if (Row.MRN == "")
{
PrimaryInsuranceCompanyIDout = primins;
}
else
{
PrimaryInsuranceCompanyIDout = Row.PrimaryInsuranceCompanyID;
primins = Row.PrimaryInsuranceCompanyID;
}
}
}
My thoughts are/were, if MRN on the input file is NULL, then I want to put the contents of primins into PrimaryInsuranceCompanyIDout. If MRN has data in it then I want to set both primins and PrimaryInsurancecompanyIDout to the value of PrimaryInsuranceID. Thanks for any help.

I just had a look at this in VS2015, which I think is a few versions ahead of yours, so my findings may not match what you see. But, when you open the Script Component's property box, you should see a node on the left called 'Input Columns'. Make sure that PrimaryInsuranceCompanyID appears here, with a usage type of 'ReadWrite'.
Once that's in place, you should be able to write to it directly:
Row.PrimaryInsuranceCompanyID = primins; etc
If you haven't even tried to resolve your issue, please don't expect the hard-working volunteers here to waste their time providing links to answers which you could easily have found yourself.

Thanks! I no longer receive an error message, which is good! But my condition never seems to be true. I changed the IF statement to if (Row.MRN == " " || Row.MRN_IsNull) but neither condition is ever satisfied. How can I tell what value may be in that column? It isn't a space and it isn't null? The file source is a csv...
