Delay in data loading

Hi,

I am loading data in an Infocube converted to column indexing using BLU Acceleration. The data has been loaded before this conversion and it took around 15 minutes for same amount of data. Now it has been more than 5 days and only quarter of the data is being loaded.

Is the delay due to Infocbue indexing being changed or can there be some other reason?

Thanks & Regards
