To join it in any report I created a temp file where I have
field1and field2 created by calling SQL statement:
INSERT INTO LIB/TEMP_FILE
SELECT FIELD1, DIGITS(FIELD1)
FROM PROD_FILE

Have you any idea how to create some logical file/view which
willhave DIGITS built in second field?
Calling SQL every time is quite painful.

Aside from the obvious and already suggested CREATE VIEW, if the data type of the numeric field is Zoned Decimal, the most efficient method to effect the same would be to create a logical file [CRTLF] from source which maps [redefines] the numeric field to a character data type and making that field a key in the logical file. The release was also not mentioned, but since v6r1, the logical file can be created instead as an SQL INDEX with the DIGITS function, and then querying the VIEW should be able to use that derived index when the TABLE is queried using SQL.
