Apparently, this code wouldn't work, because format FI ( equivalent of smallint ) is not supported in SEQNUM field. Do you have any suggestion on how do I get around this problem? We are using SYNCSORT 2.1.0
After I sequence the SID, I would be reloading the data back to the table.

FI is signed. -32,768 to +32,767. BI is unsigned. 0-65,535. If you don't have negative sequence numbers, and if they can't exceed 32,767, for your specific purpose FI and BI are the same, and you will have no problems.
I will take some time to refresh my memory on FI and BI data formats.
The idea of "unsigned binary" is known mainly among SYNCSORT/Assembler. AFAIK the most of other tools do only consider "signed binary".
The "FI,2" in SYNCSORT is equivalent to "DS H" in Assembler, and SMALLINT in DB2.
The "BI,2" in SYNCSORT is usually equivalent to "DS AL2", or "DS XL2" in Assembler, and nothing in DB2.
Any value between +32,768 to +65,535 appeared as "unsigned binary" is valid as "signed binary", too, but considered as values between -32,768 to -1 (in descending order).
The values between 0 to +32767 are absolutely equivalent in both cases. It's very unlikely that the noted TEST_SID would exceed +32767. Even if it does, I bet it is used for the purposes of uniqueness within the same TEST_ID value, so it should not harm anything.
