I have different outputs when running the file below:

TABLE FILE F3112
SUM
FST.WLSTRT/MDYY
LST.WLDRQJ/MDYY
COMPUTE DAYS_LEFT/D12.2 = LST.WLDRQJ - FST.WLSTRT;
BY WLDOCO
WHERE (F3112.F3112.WLMMCU EQ ' 4333')
AND (F3112.F3112.WLDOCO EQ 550595)
AND (F3112.F3112.WLOPSC_CODE NE 'T')
AND (F3112.F3112.WLOPST_CODE NE '20');

Output is correct:
Order FST Start Date LST Request Date DAYS_LEFT
550595 10/11/2016 12/01/2016 51.00

Removed (F3112.F3112.WLDOCO EQ 550595)from the above file.

Output is not correct:

Order FST Start Date LST Request Date DAYS_LEFT
550595 10/11/2016 11/29/2016 49.00

The output of the LST Request Date is not correct when removing and running all of WLDOCO. It should be 12/01/2016.

Any input is appreciated as to why the output is not the same when removing the WLDOCO.

When you specify a single value for WLDOCO the records don't need to be sorted once retrieved into the WF internal matrix. Without the filter on WLDOCO the records do need to be sorted after retrieval. By happenstance the records for 550595 are not sorted in the same order in both cases. So the LST operator selects a different last record in each case. Would using the MIN operator instead of FST, and MAX instead of LST give you the correct data?

The other advantage to MIN and MAX is they can be passed to SQL (if a relational DB is your data source). SQL doesn't have FST and LST, so WF cannot pass those operators and must therefore retrieve all records in order to make that determination in the summary output. With MIN and MAX SQL can perform the summary/aggregation, which will improve query performance significantly as the number of records being retrieved increases.

Updated to per your message:

TABLE FILE F3112
SUM
MIN.WLSTRT/MDYY
MAX.WLDRQJ/MDYY
COMPUTE DAYS_LEFT/D12.2 = MAX.WLDRQJ - MIN.WLSTRT;
BY WLDOCO
WHERE (F3112.F3112.WLMMCU EQ ' 4333')
AND (F3112.F3112.WLDOCO EQ 550595)
AND (F3112.F3112.WLOPSC_CODE NE 'T')
AND (F3112.F3112.WLOPST_CODE NE '20');

Output is not correct:

Order MIN Start Date Max Request Date DAYS_LEFT
550595 10/5/1901 10/5/1901 0.00

Should be:

Order MIN Start Date Max Request Date DAYS_LEFT
550595 10/11/2016 12/01/2016 51.00

quote:
SUM

MAX.WLDRQJ/MDYY
COMPUTE DAYS_LEFT/D12.2 = MAX.WLDRQJ - MIN.WLSTRT;

What format do WLSTRT and WLDRQJ have in the synonym?
I'd like to see what's displayed if you remove the reformatting ("/MDYY").

Are WLSTRT and WLDRQJ DEFINEd fields? Are the real fields date-time values?

What do you get when you run this:

TABLE FILE F3112
SUM
 FST.WLSTRT/MDYY
 MIN.WLSTRT/MDYY
 LST.WLDRQJ/MDYY
 MAX.WLDRQJ/MDYY
 COMPUTE DAYS_LEFT1/D12.2 = LST.WLDRQJ - FST.WLSTRT;
 COMPUTE DAYS_LEFT2/D12.2 = MAX.WLDRQJ - MIN.WLSTRT;
BY WLDOCO
WHERE (F3112.F3112.WLMMCU EQ ' 4333')
AND (F3112.F3112.WLDOCO EQ 550595)
AND (F3112.F3112.WLOPSC_CODE NE 'T')
AND (F3112.F3112.WLOPST_CODE NE '20');

It seems to me that your file has multiple fields named WLDRQJ in it.
Removing the WHERE-clause changes the order in which those fields are found and you're reading a different field than you were with the WHERE-clause.
