Failure occurs when running the POST command via a batch job (such as BTI) due to the invalid parameter: REQ=EXTERNAL.
Release: 12.0, 12.1
Component: WA CA 7 Edition
The POST command syntax for batch jobs does not support the REQ=EXTERNAL parameter. When you use this parameter in a batch environment, the POST command fails to process the requirement.
To successfully post an external dataset requirement(when the job is in the REQ queue) via a batch job, remove the REQ=EXTERNAL parameter and use the job name or number along with the Data Set Name (DSN) or number.
Use the following syntax for the POST command in the batch job:
POST,{JOB={jobname|jobnumber}|JOBL=longjobname}
{,USR=text}
{,DEPJOB=jobname}
{,DSN=dataset}[,INTERNAL=YES][,PREQ=(numbers,...)]
