One of the application team could not add ezplus element and reported the issue. It seems the error message issue while doing syntax checking. it was working fine. The error message follows
EZTC0744E >>> File not sequential: SYSIN+001 Dynamic allocation failed RC=00000 ezt: error opening source (SYSIN) file.
The SYSIN statement is as follows -
//SYSIN DD *
// DD DISP=SHR,DSN=&&ELMOUT(&C1ELEMENT)
Release : 18.0
Component : CA Endevor Software Change Manager
Changed the SYSIN from a PDS to PS and it resolved the problem.
