For example, if a process is set to run every time an activity is added, you will be able to access the id of the added activity.
To use the data (i.e., a field value) of the record further down the process, you need to obtain its field values using the [Read data] element. For example if the process was triggered by adding a new activity, you will know which activity is that, but will not be able to access that activity data, such as subject or assignee, unless you “read” them.
1.In the [Which data read mode to use?] field, select “Read the first record in the selection”.
2.In the [Which object to read data from?] field, select the object whose record triggered the process start signal event. For example, if the start signal event is set up so that the process starts whenever a new activity is added, select the “Activity” object.
3.Set up the following filter by the Id column and the value of the [Unique identifier of record] parameter of the start signal event:
a.Click [add] and select the [Id] column.
b.Click <?> and select [Compare with parameter] option in the menu.
4.There is no need to set up record sorting in the [How to sort records?] block, since only one record will match a filter by Id.
5.Specify the columns whose values must be fetched:
a.Select “Read data from all columns” to read values of all columns of the record.
We recommend limiting the number of columns to read data from, as reading too many columns will affect the process performance.
As a result, the added [Read data] element will obtain the values of the specified columns for the record whose Id matches the Id of the record that triggered the process. The column data will be passed to the outgoing parameters of the [Read data] element.
