First n does not with a binary load unfortunately. You have two options:
1) After binary load, resident load the required tables with some filters, then drop the original table and rename the new resident loaded table to the name of the original table.*
2) Export all the content to be loaded to QVDs, and filter the data when loading the QVDs.
* Actually the table names dont matter once the load is complete, so the table renaming may not be needed unless you are performing further transformations om the resident tables after filtering.
