> AND sp.status = 'A'

The last line of the query requires that SP.STATUS = 'A' and this makes the outer join meaningless. If there is no match in the SP table then the outer join would return a blank for SP.STATUS, but by requiring SP.STATUS = 'A' you eliminate those rows, so the query is effectively a regular join. You could eliminate the '(+)" and get the same result.

Besides eliminating blanks, the last line of the query also eliminates any rows where SP.STATUS = 'D' so those rows are not returned.
