Delta Problem

Good evening,

I have a problen with a delta of daily data upload. This morning the chain is being broken cause one of the petition of yesterday was in red too.Till here is ok but after deleting that petition in red I tried to launch a new one but I couldnt because there is one already in process but I cant find it. I cant resructure it to delete that upload which is in red. I dont know what to do cause i dont want to delete all the cube information.

Do you have any idea please?

Thanks in advance,

Reddy.
