Answer / ankan
Meta Pivot splits records by data fields (columns), converting each input record into a series of separate output records. There is one separate output record for each field of data in the original input record. Each output record contains the name and value of a single data field from the original input record.
Leading Records copies a specified number of records from its in to its out port, counting from the first record in the input file. We can Specify the number of records to copy from in port to out port.
Read Multiple Files reads records from the in port, calls a transform function to get the name of a local file from each input record, reads records from the files, and writes these records to the out port.
Write Multiple Files reads input records and derives a local filename from each single record. Each input record is written to the designated local file, passing through an optional transform function.
