Solved: 'Desired operation cannot be performed'

Former Member · ‎12-12-2008

HI,

I am using an ALV type report to show various information relating to readings of Equipment.

I wish to group the results together so that I have a total line for each different Equipment that appears on the report together with a summation of the reading's relating to the Equipment.

I am trying to use the sum functionality but I keep getting a message saying 'Desired operation cannot be performed for column 'reading'.

i have taken the field reading as a packed decimal,but when i am taking the field as a standard db table it doesn't give this error.

Any adivce is appreciated.

Thanks & Regards,
