Within the MFA User Server Task, you must concatenate the received data set HLQ.ZSERVER.SCLM.EXEC to the SYSEXEC allocation, and add the received data set HLQ. ZSERVER.SCLM.SKELS to the ISPSLIB allocation.
Instead of a static allocation you can dynamically allocate both data sets by customizing the exit procedure TAUTOXA1. See Workflow Manager Modeling Guide for more information.
Allocate every ISPF data set containing company specific SCLM routines (for example, language specific translators) to the corresponding DD statements (STEPLIB, SYSEXEC, SYSPROC, ...) within the MFA User Server Started Task.
