How to validate trailer record of input file before processing the detail records

Content

Hi Experts,

We have a requirement to validate the input file before loading, please let me know if we can achieve this in HDL FF.

The input file contains header record, detail record and trailer record. The trailer record will have the count of detail records and sum of the amount that is coming in the detail records. The validation is, if the count and sum of amount is not matching, we dont have to process the file. Please let me know is there a way to handle this in HDL FF?
