Why are you using such constructions in your query: ',' || ',' || ','  ?
May be this set of commas makes you think that some of your fields are
empty? Do you have empty fields in following query?

SELECT 'PV.LINEITEM:' || partnum || ',' || round(onhand) || ',' ||
round(qm5) || ',' || round(lsm4) || ',' || round(onorder) || ',' ||
binone || ',' || round(backorderqty) || ',' || round(onhold) || ',' ||
round(qtyperjob) || ',' || round(ordermax) AS gmrim FROM slparts WHERE
vendor LIKE 'CH%'

P.S. If you really need so many commas - use them in a single block....
',,,'
