You can use the AutoFilter feature in Smart Reference Data to narrow down the data in grids or in Selection list , which makes managing your data much easier.
How to Use AutoFilter
To use AutoFilter, click the arrow at the top of a column.
Select a value in the drop-down list. In this example, we select P_B04 in the Rule column.
The grid now only shows records with P_B04 in the Rule column.
