The file formats arrive in an RPG trigger program as a data structure. You could use a compile time array to populate an array keyed on the file name, and containing the start positions of the fields to be updated. Or if you don't want to have to recompile every time a new file is added, you could move that array out into a database file, and chain to it with the file name. if the fields are always in the same position relative to each other, you could put them in a based data structure, and use a pointer to overlay it onto the appropriate record format. Or, if necessary you could make each field you need to update a based variable, and calculate a pointer for each one.
There might be a way using SQL to do this without pointers, but since you want to use it for multiple tables, that might not work so well. When defining an SQL trigger program, it is defined for a specific table and trigger time.

Subject: Generic trigger - Dinamically field position find
I would need write a generic trigger program that update date and time
change fields ;
This is my scenario:
Trigger program receive the two standard parameter
As the date and time change fields , are always the same, (example
DATA_LOG - TIME_LOG), I would need find the initial field position in input
record update the values in the input record string with substring and then
return back so that in record I will find my date and time updated.
Can some help me with some example or how to find the initial fields
Keep in mind I have about 25 files that have the same date and time fiels
and I would like to write only one trigger program to update this two field
Thanks in advance
