Projection Data Source Designer¶
When creating a projection data source, properties in following sections need to be defined.
This section includes following configuration settings:
|Name||The name of the Data Source|
|Projection||The projection used to create the data source
This projection could be a standard projection or a query projection created via Query Designer.
|Entity Set||All available entity sets in the selected projection are listed here. Select appropriate entity set for the data source from the list.
If the selected entity set has been created with the query designer, the command "Query Designer" is enabled. This will open the query designer with the selected entity set.
|Filter||The condition to be used for the '$filter' section in the query. The condition needs to be defined according to ODATA syntax.
Also it is possible to use Page Parameters defined in the Page Properties Configuration dialog.
E.g. Company eq $COMPANY$.
(Remember to append the $ sign for page parameters)
|Group By||The column to be used to group the data|
|Order By||The column to be used to order the data. Default is ascending.|
