What is a drill-down report?

Drill-down is used for navigation in hierarchically organized data (OLAP). Drill-down describes an increasing granularity in the management of data. E. g., one can zoom into an address. The process of zooming out (decreasing granularity) is called roll-up or drill-up. The drill-down’s increasing granularity is shown with the help of an address example that develops from the country (low granularity) to the real address (high granularity).The drill-up or roll-up is the opposite of a drill-down. It makes use of a decreasing granularity showing things more globally.

Following the items in the picture from top to down you can see the increasing granularity of the drill-down whereas the down to top direction shows the decreasing granularity of a roll-up / drill-up.

Documentum differentiates between two kinds of drill-down reports:
Single Drill-down Multi Drill-down
relation between a base report and a target report: base report is updated based on target report Link a base report to other reports: relation results in an updateBut one of the surrounding dashlets not one of the contents of the base report (E20-120 exam)
Built in one phase:
use Process Reporting Services to implement relation between base and target		 Built in two phases:
1. use PRS to build the hyperlinks
2. use Task Space dashboard manager to implement the connection between the dashboards to be updated and the source

Single- and multi drill-down reports are configured with a source (base) report and a target report. It is best practice to design the target report first, so that it is available on picklists when the source (base) report is designed.

What is the Document Image Services?

What is... This is a short answer and question category.

Explanation:With the Documentum Document Image Services (DIS) imaging-related documents and pictures can be viewed in the Taskspace or Webtop application without opening external programs. DIS provides some third-party viewers like IGC Brava! or Daeja ViewOne Pro for viewing, annotating and streaming content.

Function: The Documentum Document Image Services is an image and document viewing framework and available for all WDK Image viewer control applications (eg. Taskspace).
DIS was released for Documentum 6 and is available for Documentum 6.5, 6.6 and 6.7 and will be part of the Documentum 7 applications.

The Brava and Daeja viewers provide similar page access functionality, in which the viewer may be able to display the first page of a document before the entire document has been downloaded from the server. The page serving functionality built into ACS and BOCS using page aware plug-ins. ACS and BOCS can split a multi-page file into individual pages and serve them back to the viewer if the viewer requests it (only available for PDF and TIFF).
The page modifications functionality built into DIS and TaskSpace is used for document merging and page modifications such as deleting, inserting, splitting, and reordering pages in a multiple page document.

What is the server step size?

 

What is... This is a short answer and question category.

Explanation: The server step size is a numeric value in seconds. It displays how often information from the audit trail table will be transferred into the BAM database.

Function: The numeric value is the period how often the event pipe job runs. You can increase the step size on high volume environments.
Please keep in mind: the server step size and the data transfer latency are asynchronous but dependent entities. On high volume environment increase the latency and the job runs less frequently. The job takes longer and the data size of each transaction is larger. Do not increase the step size to much, because the data size and data volume could have negative effects to the system performance.

Understanding Process Data

Understanding Process Data

xCP 1.x compatible

There are three kind of process data used in Process Builder:

  • Package attributes are the metadata associated with the object
  • Process variables can be single attributes or a complex hierarchy of attributes named Structured Data Types (SDT)
  • Process parameters are predefined values used in all instances

Packages

Packages are metadata associated with the Documentum object which is passed between activities in an existing process. Package data is persistent.

Process variables

Process variables are not persistent. This kind of variables must be mapped in the Process Data Mapping Activity to a package attribute if the value of the variable should persist beyond the life of the process instance.

Structured Data Types are not persistent. They are global and can be used by any process.
It is not possible to delete or modify used SDT attributes. New attributes to an existing SDT can be added. SDT should be used to group logically related business data.
SDTs are more lightweight than object attributes and are better for performance and scalability. Replace as many process variables as possible with SDT attributes (xCP Performance Tuning Guide).

Process parameters

Process parameters are fixed values defined in the process template and available for all process instances. Administrators can change process parameters without uninstalling the process. The changed parameter value is used in all process instances after saving the value.

Any changes to the data model require uninstalling, saving and reinstalling the form and process templates. 
Example: to change a SDT or SDT attribute after implementing you must break the data binding in Forms Builder and rebind the renamed SDT.

Updating process data

To modifying an SDT  – variable it brings a lot of trouble in your environment.
To change the SDT properties you must delete the selected SDT from the environment and recreate the SDT including the old properties and the changed properties.

Modifications:

  • remove an attribute from the SDT
  • decrease the length of a string value (increase the length can be done at any time)
  • change the type of an attribute
  • change from repeating to non-repeating
