Define Import Specifications - the Fields (2) Tab
You can use this tab to define fields based on the fields in the Fields (1) tab.
These fields will be processed further, depending on the result of the Fields (1) during import. This is useful if you want to process a value further in an aggregated form.
For example, in the Fields (1) tab, all account codes X are converted to the account code A by running a lookup table. In the Fields (2) tab, the sum of all accounts A is analyzed and if the total value is positive, the value is converted to the account code A, otherwise it is converted to the account code B. This is done by connecting the field to an operation template containing the Lookup Split operation.
Note: In most cases it is enough to use the Fields
(1)tab.
