Trying to use the case function in Derived Column

Trying to use the case function in Derived Column

(OP)
Im using SSIS 2012.
This is the expression that I have on my field. The paymethod field is char field of length 1
I am trying to say if it = C then put "CHK else "EFT. How can I write this expression when I want the output to be 3 char.
The following give me an error
[Flat File Destination [35]] Error: Data conversion failed. The data conversion for column "PayMethod" returned status value 3 and status text "Text was truncated or one or more characters had no match in the target code page.".

(DT_STR,3,1252)(PayMethod == "C" ? "CHK" : "EFT")

If I do it like this it works but I need the "CHK" and "EFT"
(DT_STR,1,1252)(PayMethod == "C" ? "C" : "E")

RE: Trying to use the case function in Derived Column

did you tried (DT_STR,3,1252)(PayMethod == "C" ? "CHK" : "EFT") ?

RE: Trying to use the case function in Derived Column

You may have to trace your data all the way through the package to find where this is having a problem. I would start by looking at the flat file connection manager, on the Advanced tab, and verify my data types and sizes were good there.
