Format Mask Mapping for Target Values

Use a format mask to define a target member based on a combination of source member details, and optional user-defined text. For example, use a format mask to designate a target member based on some part of the source member, an additional prefix, suffix, or replacement text for the target.

The format mask is available for the target member specification for all mapping types except explicit. Common usage of this mapping type falls into three categories: replacing segments from the source, replacing segments with string operations, and replacing segments with string operations using a prefix or a suffix.
