delta load error

Hi experts,

Assuming that i am loading deltas daily to 3 cubes in parallel from the infosource 2lis_11_vaitm ( for that matter any infosource) and the deltas go through well for first 6 days and fails on the 7th day for one cube. how will i load delta to that particular cube now and i dont have data in psa too for that day. could someone throw some light on this issue. do i need to do re-init.
