Hi Experts,

In my Account receivable report there is field called Amount in 2nd Local currency(0DEB_CRE_L2) which shown wrong values for one particular document in bex analyzer which is getting values from infocube.I checked data source,dso and infocube for this particualr document where it is showing correct value when compared to R/3 value.
