Processing fixed width file in Informatica PowerCenter is not a big deal. But this can be bit tricky if the fixed file contins both multi byte and single byte characters such as unicode characters. This is because of the fact that fixed width flat files are byte oriented, which means the field width is measured in bytes. So if a single character takes two bytes for its representation, it will be treated as width two. In this article, lets see how such files are handled in Informatica PowerCenter.
Lookup transformation is synonymous to SQL outer join, which is primarily used for relational and flat file data source lookups. But with the introduction of pipeline lookup, we can use all variety of data sources in the lookup transformation. This feature is really powerful just like Active Lookup Transformation. In this article lets see how pipeline lookup transformation can be configured in a mapping.
