If you plan to use the Reconciliation data file, establish Generation Data Groups to define its data set names. This allows you to avoid continual JCL modifications to CAKRLOAD.
For example:
//RECON DD DSN=PMA.RECON.DATA.FILE(+1)
This JCL outputs a new Reconciliation file each time CAKRLOAD is processed.
Optional processing can be achieved by sorting the ORD Data File prior to input processing.
