Miscellaneous

The Miscellaneous section is displayed on the Data Source tab when the Object Model Rollup Engine Provider is selected on the App Part tab..

This section contains the following options:

1. Use the Limit Amount Of Items Return To text box to restrict the number of items returned from the data source. Use this option for performance reasons. This limit will be applied to the first X amount retrieved from the data source.
   
   
2. Limit Amount of Items Returned Per List will also restrict the number of items returned from the data source, but based on each source list separately. Also use this for performance reasons.
   
   
3. Retrieve Missing Parent Folders If checked, then the rollup engine provider will additionally retrieve parent folders (also items) for all rolled up items, which are missing among rolled up items. Such situation could occur if the parent item(s) does not satisfy the provided filters or are missing because of a specified item limit, etc.
   
   
4. Retrieve Missing Parent Tasks If checked, then the rollup engine provider will additionally retrieve parent tasks for all rolled up task items, which are missing among rolled up task items. Such situation could occur if the parent task(s) does not satisfy the provided filters or are missing because of a specified item limit, etc. If the users want to render all displayed fields also for all rendered parent task(s), then by checking this option, the rollup engine would additionally retrieve all missing parent tasks of all tasks included in the rollup.
   

Pagination on the Display tab can be set to return a specific subset. For example, if you would like to show the “Top Ten latest Announcements”, instead of typing a number in the Limit Amount Of Items Returned To text box, use the Paging Configuration section on the Display tab. Then, on the Columns tab, sort by the column, Created, in descending order.
