Answer / amit
Join logical file is just a view created using multiple
files. It can't be updated as its not a view similar to
logical file but its a view that represent aggregation of
more than one record format.

Answer / kolla ravi
When you talk of Update of a Join logical file it can be
when you mean to use CHGLF and associate differrent PF
Member or modify any attributes.
If you ask about the Join Logical file Data (i.e pointed
by) held within its members then it Cannot be modified.

Join logical file can't be updated, because it is related
with more than one PF as multi format logiacl file.

Answer / nagarama
For the selected fields, it can retrive multiple records
from File2 for the single matching record in File1. So
updating is not logically possible if it has to update the
values in File2 fields (this is an example). So, in the
broad sense sysetm will no allow the updating Join logical
file.

Answer / jherie
We can't update a joint logical file directly, simply
because it is a logical file. It creates an access path for
multiple physical or logical file.
But if we update the physical file in which joint LF is
pointing to, it will automatically be updated.

Answer / avinash
We can not update the logical file. but when we do changes
in physical then if record format of logical file is same
as physical file then no need to be recreate it again. but
if if phyical file format is different with logical file
format. we have to recreate the LF.
