Within the MFA User Server Task, you must concatenate the received data sets HLQ.SCLM.CUSTOM.EXEC and HLQ.SCLM.EXEC to the SYSEXEC allocation, and add the received data sets HLQ.SCLM.CUSTOM.SKELS and HLQ.SCLM.SKELS to the ISPSLIB allocation.
Instead of a static allocation you can dynamically allocate those 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, and so on) within the MFA User Server Started Task.
