I'm still missing something in your example.
Let's create a simple example and then you can provide the exact missing
CREATE command.
Table is created with the following.
CREATE TABLE MYLIB/MYTABLE
(
FIELD1 CHAR (10),
FIELD2 CHAR (10),
FIELD3 CHAR (10),
FIELD4 CHAR (10),
PRIMARY KEY (FIELD1, FIELD2)
)
RCDFMT MYTABLERCD
How do I create a view/index/whatever with only records where FIELD3 = 'X'
and Ordered by FIELD4.

You CAN create an index with a WHERE clause. IBM specifically made this to
eliminate 99% of the arguments people had against SQL.
Sample:
Vendor creates table (let's call it IIM for an item master table). Vendor
puts no key on the table. Table has an active record column (IID). Vendor
creates a logical file in DDS like this
R IPI100IM PFILE(IIM )
K IPROD
S IID COMP(EQ 'IM')
Of course the vendor is an a$$ who thinks their program logic will ensure
there are no duplicate keys and whatnot.
Several releases ago IBM came up with this in sql
create index rob.iiml01
on erplxf.iim (iprod)
where iid='IM'
rcdfmt IPI100IM add all columns
