Which is not a valid step in defining the import format in data management?

Setting target application column names is not considered a valid step in defining the import format in data management. The steps involved in defining import formats typically revolve around how data is structured within a file and how it is mapped to the destination system.

Defining the file type as fixed, delimited, or multi-column is crucial because it influences how the data parser reads the file. This includes understanding whether each line has the same number of characters (fixed), if there are specific characters that separate data (delimited), or if the data is structured in multiple columns.

Defining the file delimiter is another critical aspect, as it allows the system to understand how to separate different fields within the source data. For instance, knowing whether commas, tabs, or other characters are used to delimit data fields is essential for accurate data parsing and importing.

Defining the source and target is an important step because it establishes where the data is coming from and where it will be placed within the system. This mapping ensures that the fields in the source data correspond correctly to the fields in the target application.

In contrast, setting target application column names directly affects how data is referenced or displayed in the application but does not fall under the initial definition of import format. Rather, it would
