There are three steps in submitting a BATCHREP job.
If you are directing the output to a partitioned data set member, you should ensure that the data set has enough directory entries and space to successfully execute the command. Failure to do this could cause the CMAS to terminate.
Submitting a batched repository-update job that processes the same definition in quick succession may result in one or more control statements failing. In such circumstances the best procedure would be to divide the repository-update job and submit the resultant jobs sequentially.
