AX 2009 - Reports - column sum

hi,

I have problem with column sum in two standard reports from AX 2009. AssetAcquisition has column AcquisitionPrice with properties SumAll: Yes, also AssetListing reports has properties SumAll: Yes on dataMethod AssetNetBookValue.

On reports AX doesn’t show sum line. Why ?
Is there any additional option to set ?

Best regards,

Jacek
