We have finally come to the last section of this chapter.
We have the field of 'Data type' for all the dimensions. When we create a web form and wish to view data for a combination of dimensions, then we need to tell the system which data type to use.
For example, there is an account member whose data type is percentage and anentity member US, whose data type is Currency. Now, we are looking at the form which has these two members along with other dimensions too. Now, are we not confused in understanding what data type would be reflected when we look at the data values. The order is the key here, if the Account dimension is above the Entity dimension in the evaluation order, then the Account dimension has precedence over the Entity dimension.
Another example, say we have an Account member set to Percentage as its data type and it is used in a form. To display the member using percentages, we need to place the Account dimension above in the data type evaluation order.
