Baseline should include a snapshot of assignments.

[#1]

Currently Baseline contains information at project level and at task level, but does not include assignments. The objects currently only snapshot BLIN (project level) and BSTSK (baseline task level), but no ASSGN (assignment level). Why not copy the current assignment records from TASK level to a new on in ASSGN that is referenced by the BSTSK (baseline task level)? This would give the possibility of comparing Baseline planned hours by role to the Project actual hours by role so you can see variances of original plans by role to actuals.
