SSIS Data Flow - sequential insert with required foreign key values

See more:

SSIS

Is it possible to insert to a initial table then using the inserted ID to be used in inserting to the main table that has a foreign key constraint between the columns in one data flow?

I am new to integration services and don't know the capabilities

Scenario:

TABLE A - ID - DESC

TABLE B - ID - A_ID - DESC

This is where A_ID is the foreign key (if its not obvious)

Can i create a single data flow with this kind of sequential flow of events or do I need to create another data flow for insertion of TABLE B after I inserted in table A.
