Re: multiple delimiters in output
Hi Neeraj,
One way of achieving this is by using tMap and tDenormalize combination.
We will have three sub jobs one to read each input file. Each sub job will denormalize the corresponding input. The output of each sub job will appended to the same intermediate output file. (In the screen shot tFileOutputDelimited_1, tFileOutputDelimited_3 and tFileOutputDelimited_4 refers to the same file with the schema U_ID;SCode_SName;JCode_JName;QCode_QName).
Once the three input files are denormalized, we can aggregate the intermediate output file grouping by U_ID and taking MAX of SCode_SName, JCode_JName and QCode_QName columns to generate the required final output.
Regards,
Abhi
