To use the #FORMAT mapping type:
On the Workflow tab, under Data Load, select Data Load Mapping.
In Source Value, enter the segment to map.
For example, on the Like tab, enter: 12345-6789-012-3456ABC-001 in the Source Value field.
In the Target Value, select the format map for the target member using this format: #FORMAT(<format mask>, <segment delimiter>).
For example, enter #FORMAT(“???-*-GROUP-AA##?#*X-GROUP”,”-“).
To reverse the sign of the target account specified, select Change Sign.
Select Apply to Rule to apply the mapping only to a specific data rule in a location.
By the default, mappings specified at a location apply to all data rules in a location.
The result of applying format map created in steps 5 and 6: 123-6789-GROUP-AA5ABCX-GROUP.
