Is it possible that we can manage a specific translation table with an XFB application or in a PELTRANS JCL? Do we need a parameter or a definition on XFB or transfers? We are using PESITH2 protocol

It is quite possible to create Translation tables. I am providing you the System Programmer Reference Guide. This manual provides an indepth discussion on how to create translation table. The information you are requiring can be found in the "CONVERSION TABLE CREATION" on page 5-1.
