Error in Consumption & issue for materials

Hi Team

I was  observed  that due to excess or wrong   entries of goods issue & consumption booking, system showing wrong store clearance report in  xxx client .

For example

1. Issue (311) – 1314 Sqm and  issue return(312) – 1573 sqm

  Consumption return 489 sqm where as there is no issue.

Let us know which entries should  we delete  so that system will show the right store clearance  report.
