Failed Chain question.

Hope this makes sense

We have a lot of old code on our system and I have a bit of a block on
what I think can be an issue but I'm not sure if I dreamt or not.

This code doesn't make much use renames etc so files tend to share field
names. The point is this, when chaining to a file and you don't get a
match can the field values from the file of the failed chain overwrite
the same named field values in the program ? I seem to think it can but
I'm not 100%.

E.G.

Field Prdid is used in more than 1 file and shares the name throughout.

Say Prdid = 'A' from a previous file or move etc.

Chain to another file that contains the field Prdid fails, can the
value of any of the records on this file overwrite the value of Prdid
even though the chain actually failed.

Thanks
