When a normal run is proceed user can do a correction run. This correction run can be merged to a normal run. You can merge as many corrections as you want over the same period.
After the merge, the run ID of the normal run will always be kept.
For example: You run period 1, this run has ID 101. You run correction over period 1, this tun has ID 202. When you merge runs, the run will have ID 101.
