Whats the best way in a AI GRAPH to read the header 1st line and trailer (last line) in a i/p file, compare record counts and checksum (available in header) and error out if actual recd count or checksum did not match?

we can use run compononent in the parameters tab for commandline give unix AWK command for skipping the specified record num

awk '{if(NR!=1  && NR!=2) print $0}' this we can use for first record

or else we can use onemore component read seperated value in the parameters tab u can specify skipheader as true

This is upto my knowledge

Thanks

If the input dml has record type, simply do FBE will do.

If the input dml has no record type, but with "n" as End of Record, do a wc -l up front and pass the result back to the graph will do the trick.

Otherwise, you need to assign a sequence number (next_in_sequence) using Reformat, also capture the log port for the record count.  Then:

Header: sequence number=1

Do a join with the source data (say in0) and from the record count capture from the previous Reformat log port (say, in1).

Trailer: in0.sequencenumber=in1.reccount

guys,

 to read header ,detail,trailer from input file separately ,do validatins for these,

use conditional dml,where we can separate detail from header and trailer

for validations u have to use reformat with count :3(out0:header,Out1:detail,Out2:trailer.)

if any doubts further let me know

cheers

You can also use a keyless Dedup with keep parameter as first.
This will put header in output port and rest of the record on Dup port . Then connect dup port again with another dedup and use Keep parameter as last this will remove trailer as well.

anujaja, use only one dedup sort. in dedup sort use the select statement "next_in_sequence > 1" and use keyless Dedup "{}".  With keep paramete "last". this will remove trailer, you will get all the body part from the "dup" port
