Ans1 : We can use Read Method = “Specific Files” and give the full path of all the file one by one. Alternatively, you can use Read Method = “File Pattern” and specify the wild card.
Ans 2: We can control this using “Missing File Mode” Option. Values are “Ok” to skip the file and continue and “Error” to abort the job.
Ans3: It is important to make sure the meta data matches the record. It would be better to reject bad reject and collect them in “Reject Link”. This can be controlled by “Reject Mode” option. Values are “Continue”, “Fail” and “Output”. “Output” will collect the reject records in a reject link.
