This function can be used to convert an aggregate map a into a 'normal' map b. You can then work with the 'normal' map as usual. It is also shown in a mapping test.

The aggregate map a is then deleted.

The return value of the function is the number of entries of the generated map b.

Parameters

Parameter	Description
a	Name of the aggregate map to be converted.
b	Name of the 'normal' map to be created.
c	The separator within an entry in map b that is used to separate the values of the different groupings.
d	(optional) A sorting of the groupings within an entry in map b can be specified here. Example: desc(2) creates a descending sort (ascending with asc) based on the values of the second source structure field. Multiple sortings can also be carried out, e.g. with asc(1),desc(2) . Note: See also subsection "Sorting" in section Special nodes for aggregate maps in source structure.
