You can configure the target fields that you want to use in the data flow. You can add and remove target fields, configure how the fields are displayed, edit field metadata, and restore original fields from the target object.
Configure target fields on the Target Fields tab of the Properties panel.
You can configure target fields in the following ways:
Add and remove fields.
You can add fields to a mapping target. To add a field, click Add Field, and then enter the field name, type, precision, and scale.
You can also remove fields that you do not want to use in the mapping. To remove fields, select the fields that you want to remove, and then click Delete.
Change the sort order.
You can display target fields in native order, ascending order, or descending order. To change the sort order, click Sort, and select the appropriate sort order.
Use technical field names or labels.
You can display field names by label or technical field name.
To change the display option for field names, select Options > Use Technical Field Names or Options > Use Labels.
Edit field metadata.
You can edit the metadata for a field. You might edit metadata to change information that is incorrectly inferred. When you edit metadata, you can change the name, native type, native precision, and native scale, if applicable for the data type.
To edit the name or metadata for one or more fields, click Options > Edit Metadata. When you edit metadata, you can also display native names by label or technical field name. To change the display option for native names, select Options > Show Technical Field Names or Options > Show Labels.
When you change the metadata for a field, avoid making changes that can cause errors when you run the task. For example, you can usually increase the native precision or native scale of a field without causing errors. But if you reduce the precision of a field, you might cause the truncation of data.
You can't edit field metadata in mappings in SQL ELT mode.
Restore original fields from the target object.
To restore the original fields from the target object, use the Synchronize option. When you synchronize fields, Data Integration restores deleted target fields, reverts data type and precision changes, and adds fields that are new to the target. Data Integration removes any added fields that do not have corresponding fields in the target object.
For existing target fields, Data Integration replaces any metadata that you edited with the field metadata from the target object. Data Integration does not revert changes that you made to the Name field.
