hello Experts,

i have a problem where i want to convert an array of numbers and characters to string. i am not sure which conversion block to use as byte_to_string is not supported in cfc get the error sy_array type is not supported. Dint to string, real to string none of this conversions provide the required output. could some one please guide to resolve this.

This is impractical (and likely impossible) to solve direct in CFC.  I suggest you need to create a custom block (in SCL, etc.) in order to deliver the solution.  As array is not supported in CFC you need to connect to the DB or bulk I/Q space from a PN or DP slave which will need parsed from the custom block.  Architecture of such a block could be easy or complex depending on the details of your data.
