Hi Sorin,
Again making little confusion.
One thing i want know that is.
1. You deleted records based on selection or
2. You deleted whole request?
in general 3.x if we delete whole request id from cube level due to bad or invalid data,
we do the correction at psa and will reload the samre request by using update from scheduler or reconstruction.
Based on above points you choose the best way to reload.
As my guess other than reloading thru repair full info pack there is no option for to load data selectively.
Thanks
