Alternative fm for RZL_READ_DIR_LOCAL

Note 1595074 added a new authorization checks to fm RZL_READ_DIR_LOCAL, so I can't use it anymore.

I'm looking for a new standard function module or method (released by SAP) to retrieve file from application server.

System function (<CALL cfunc >) statement is for internal use only, it cannot be used in application programs.

thanks
