The Attribution Dimension setting applies only to tables that are related through a chasm trap. If your schema does not include these, you can ignore this setting.
The Attribution Dimension setting only applies to tables that join over a Chasm Trap. By default, the attribution dimension setting will be set to Yes, but you can override that by setting the column's attribution dimension property to No, as described here.
In the classic chasm trap two fact tables are related through a shared dimension table. When the two fact tables are joined, the shared column(s) in the dimension table are used to attribute rows in one fact table to match with rows in the other fact table. Usually, all goes well using this method. But sometimes an incorrect or illogical attribution can result, because the column chosen is not meaningful for performing this attribution. If you are seeing unexpected results in searches that include tables across a chasm trap, this setting is for you.
- Find the column that is not an attribution dimension and select its Attribution Dimension.
- Set the value to No.
If you're using the modeling file, set it to FALSE.
- Save your changes.
