i have headers separately, how to import it to informatica target -

i have source , target in informatica powercenter developer. heed other header name imported in target file automatically without manual entry. how can import customized headers informatica target.

what have tried?

you can use header command in session configuration target, haven't used it, , couldn't find documentation on (i.e. possible , how, whether parameters can used or not, etc.). did test using (on windows) echo command output text header row, didn't seem recognize parameters.

or can try include header first data output row. means output have string types , length restrictions may compound issue.

or can try using 2 mappings, 1 truncates files , writes header , 1 outputs data specifying append in session. may need 2 target definitions pointing same files. don't know if second mapping attempt load existing data (i.e. typecheck), in case might throw error if didn't match.

other options may possible, don't flat files.
