Posting change notice deletion

Dear All,

I have small problem with clearing LL01.

I have one posting change that I can't delete.

I can't do it via LU02, because destination and source data are the same and I can't change it.

I can't also cancel document via MIGO, because there is no stock.

To keep clean posting changes is one of my new KPI, so I have to find a solution, but standard procedures doesn't work.

Thanks in advance
