Excel DAX - Deleting a Calculated Field
您可以删除显式和隐式计算字段。有几种方法可以做到这一点，您将在本章中学习这些方法。
You can delete both explicit and implicit calculated fields. There are several ways of doing so, which you will learn in this chapter.
但是，在删除计算字段之前，您需要记住以下几点：
However, you need to remember the following points before deleting a calculated field −
-
An explicit calculated field can be used in more than one PivotTable and/or PivotChart. Hence, you need to make sure that deleting the explicit calculated field does not affect any of the reports that you have already generated.
-
An explicit calculated field can be used in the calculations of other explicit calculated fields. Hence, you need to make sure that the explicit calculated field is not used in any of the calculations of other explicit calculated fields.
-
An implicit calculated field is limited to the PivotTable or PivotChart where it is used. Hence, before deleting an implicit calculated field, it is just sufficient to make sure that it can be deleted from the corresponding PivotTable or PivotChart.
-
Creating an implicit calculated field is simpler than creating an explicit calculated field. Hence, more caution is required before deleting an explicit calculated field.
-
You cannot create an explicit calculated field, if the name conflicts with the name of an implicit calculated field. Hence, you might have to delete that implicit calculated field before creating the explicit calculated field.
