Hi, we met a issuse when using dataflow in Pega Marketing 7.21.
We used as following, more information can be reviewed in attachment file:
1) we created a dataflow X_DF in class A. It work well, and get the result expected.
2) we created a dataflow Y_DF in class B(another class), and X_DF was used as a secondary data source (not a primary source). But as a result, X_DF can not get a record this time.
Is there some problem when using like this.
In help file, it has the following description [Secondary sources are added as you start combining data. Secondary data sources can originate from a data set, data flow, or report definition.] May I use a dataflow in another class as a secondary sources?
Use the compose pattern to combine data from two sources into a page or page list property. This pattern requires a property to match data between the two sources. The starting data point is the shape from which you start combining data. After the compose path is available, you can define the secondary source by providing an existing data set or another data flow.
Accodring to above, I believe that you can use data flow from a different class as a secondary source.
Could it be that no matching property was found between the two sources and hence no result found?
