I suspect that what you want is something like the following. You
cannot used the same table reference in both the main query and the
subquery.

SELECT
DOCLINE.DOCLINE_ID,
DOCLINE.ITEM_ID,
DOCLINE.DOCLINE_QTY,
DOCLINE.DOCLINE_TOTAL_VALUE,
(
SELECT SUM( DL.DOCLINE_TOTAL_VALUE ) FROM DOC DC
INNER JOIN DOCLINE DL ON (DC.DOC_ID = DL.DOC_ID)
WHERE
(DC.DOC_ID < :DOC_ID) AND (DL.ITEM_ID = DOCLINE.ITEM_ID) AND
(DC.PROJ_ID = :PROJ_ID)
)
AS PREVIOUSLY_INVOICED,
DOCLINE.LOC_NAME

FROM LOC
 RIGHT OUTER JOIN ITEM ON (LOC.LOC_ID = ITEM.LOC_ID)
 INNER JOIN DOCLINE ON (ITEM.ITEM_ID = DOCLINE.ITEM_ID)

WHERE
DOCLINE.DOC_ID = :DOC_ID
