Not having used a BICA load my knowledge is limited but ...
The "onerror cont" tells the job to keep running even if it hits an error. This implies the author of the procedure expects the BICA_SETLATEST file might be missing and so it is not a fatal error
I guess BICA_SETLATEST is meant to be a procedure whose purpose is to set the latest date. Why it is present in some instances and absent in other is a mystery to me. However you might want to create your own. It can be a procedure with one line of code
set latest Dec 2014
or whatever date you want to be the latest. Latest is a variable that acts like the LASTDATE doc. Some processes use one and some use the other. Latest is used mainly in PAS jobs such as load jobs.
