error in compare stage

[ggs]

A job containing 2 input files ,1 output file and 1 compare stage.while running this job i am getting error :

"main_program: Fatal Error: Attempt to drop schema variable: "first.rec"; this may be due to dropping a subrec which contains a schema variable; this operation is not currently supported; to work around this limitation, insert a copy operator between the modify and the upstream operator"

can any body help me regarding this?

Looks to me like you are doing an explicit conversion with RCP on. So it is dropping the original field due to field name conflict and asking you to drop it in a copy stage. Swith off RCP and try.

Output file does not support vector records. try dataset and check

Thanks Madhukar,
here i am explaining my job in detail:

a)First Input: Sequential File :
Field 1
Field 2
Field 3

b)Second Input :Sequntial File :
Filed 1
Field 2
Field 3

c)Comapre Stage :

d)Output: Dataset

Field1 values are differring in both the input tables.
Here the output should contain the data in both the input files .

How can i go ahead?
