Issue with Occurs clause Variables

We are migrating Micro focus COBOL programs to IBM COBOL for my client(shop direct). We see some initialization errors coming from mx20f program while compiling with IBM COBOL compiler.

Initialization is not possible on occurs clause variables in IBM COBOL. Do you see any option which can solve these compilation errors similar as MF COBOL? Please check and suggest.
