I was trying to use Write back BADI for dis-aggregate function in an input template. The input template has time in row axis and projects(user defined dim) in column axis.
It is the understanding that for each values provided in template there will be a record in ct_array. but ct_array contain additional records corresponding to the root of the project also.
In current view of the template only project dimension is taken in multiple levels(parent & child) and all other dimensions have base nodes values.
