FAGLB03 shows incorrect balance in drill down vs CUM BALANCE

Dear Expert,

SAP Tcode FAGLB03

When clicked into the “cum. balance”, the total transactions amount shown are not same as displayed .

I checked line item display in gl master data has just been activated on 01.07.2021,meaning, earlier transactions

posted before 01.07.2021 will not be displayed in the line item report. SAP only shows transactions posted

on 01.07.2021 & onwards.

Please advise us on how this issue can be resolved.

Regards

GG
