Convert between Datatypes in Hana Expert routine

Hi,

i'd like to implement a Hana Expert routine between 2 adsos.

Lets say the source adso has an InfoObject /BIC/XLA of type char 16. The corresponding InfoObject in the destination adso is /BIC/XLB of type 16.

So the transformation is /BIC/XLA = /BIC/XLB.

How can i do this in the Hana Expert routine?

I thought of something like:

outtab = Select "/BIC/OIXLA" ,

                    FROM :intab;

But it won't work.

Do you guys have any ideas?

Thanks,

Tobias
