What is the best solution for a data capture issue, where the source tables don't have proper timestamp capture for the updates?

Q: We are in the design phase of a data warehouse, stuck with a change data capture issue, where the source system is JDE and the source tables don't have proper timestamp capture for the updates and inserts, which deprives us of proper incremental load capture. It is not an option to use the source transaction logs for change data capture. A third option of full-table comparison leads to major overhead, so even that is ruled out. What would be the best solution other than the three options above? Do you have any suggestions regarding the "check sum" method? How feasible is the method and how would we achieve it?
