Sql queries from internal tables based on context node

Question

Hi experts,
I want to select from my inetrnal table which is based on the context node, the rows which do not appear in another internal table based on the context node.
I have this data:
data lt_item_level type table of wd_this->element_item_level INITIAL SIZE 0.
data lt_item_level_cp type table of wd_this->element_item_level INITIAL SIZE 0.
data lt_po_items TYPE table of wd_this->element_po_items INITIAL SIZE 0.
I want to do this:
select * into CORRESPONDING FIELDS OF TABLE lt_item_level_cp from lt_item_level WHERE lt_po_items-po_number NE lt_item_level-item_number.
But i get an error:
"LT_ITEM_LEVEL" is not defined in the ABAP Dictionary as a table,
Is there a way to do it with select or should i loop over my internal tables?
thank u very much!!

hi,
You cannot use Select queries on internal table.  do like this :
loop at itab into wa where wa-F1 NE wa-F2.
append wa to itab1.
endloop.
Here itab1 will have all the records as per your requiement.
I hope it is clear.
