insert a space in a string in automatic basis after every 2 characters

Hi experts,

I have a string which is returning a value with different length for each system

and I need to return that value in a report with a better layout for that I need to insert a space in between every 2 characters, how can I do that?

example: original string value = D2F2G1V0E0M5B3

how I need to return it = D2 F2 G1 V0 E0 M5 B3

the problem is: the length of the original string is different for each system

thanks in advance and best regards,
