The index on this cursor serves no purpose.

This is where you need the index... and if you create a similar index as above, you need to use the exact same filter in your WHERE.
So... if you do
INDEX ON po_code + po_docode TAG someTag

your WHERE should be something like this
WHERE po_code + po_docode = tmpLoad.PROD + 'x'


> UPDATE xxx;
> SET po_area = tmpLoad.area;
> WHERE po_code = tmpLoad.PROD AND;
> po_docode = "x"
