application log or spool message

Hello People,

I want to know best practices regarding implementation of batch/background programs.

My question is:

1. Do you use any error mechanism if sy-subrc fails e.g. en-queue function module fails and return sy-subrc = '1' ... in that case do you just terminate your program or use some error mechanism and then terminate it (I want to know industry best practice).

2. Also which is the best error mechanism available (easy and performance oriented)

i.e. app. log, bpem or simple spool message etc.

Any documentation/url would be of great help.

Kind Regards,

Nikhil J.
