Cascading vs Interdependent LOV

Cascading LOV

Cascading LOV or hierarchical LOV is an LOV whose values have their own sub-lovs. In Teamcenter, the cascading lovs are display as levels. We can setup multiple levels of values, the final level value selected is stored as property value

Foe example, to define city property with cascading lov of st level as country, 2nd level as states and 3rd level as cities.

Steps to create cascading LOV

Create a main classic LOV to hold the sub LOV's. All the values of the main LOV should have a sub LOV assigned. For example, in main LOV create with state names as value, then create sub LOV for each state with city names.

Main LOV

Open the main LOV created in BMIDE. Select the Show Cascading View check box. Cascading LOV view is not shown unless the check box is selected.
Select a value in the main LOV and choose sub LOV. In the LOV selection dialog box, select the sub lov. In case not created, create the sub lov for each value in main LOV.

Sub LOV

Cascading View

Attach the main LOV to the property using LOV attachments section.

Cascading view and LOV attachments

Interdependent LOV

Interdependent LOV is to display the list of values for a property based on a value selected for other property.

For Example, to define states and city property. Based on the state value selected, the city property list of value should be displayed.

Steps to create Interdependent LOV:

Create a cascading LOV by following the steps from Cascading LOV.
Open the main LOV created in BMIDE. Select the Show Cascading View check box. Cascading LOV view is not shown unless the check box is selected.
Ensure the cascading LOV is attached to a property in LOV attachments table.
Select the attachment in the LOV attachments table and chose Edit.

Attachments Edit

Interdependent LOV dialog box appears. Select the property and click Attach.

Interdependent LOV dialog

Select the interdependent property.

Interdependent LOV attachment

Save and deploy the changes.

Differences between Cascading & Interdependent LOV:

In cascading lov, only the final level values is stored in property (i.e, in database). We cannot track back the hierarchy for any validation or for any custom logic.
As Interdependent lov captures the main and sub lov in different properties, all values are stored in teamcenter properties (i.e, in database)

Teamcenter Relations

Teamcenter Relation objects are created to relate two objects. It connects the primary business object and secondary business object through relation property. Relations are widely used in Teamcenter. Out of the Box Teamcenter provides various relation objects to relate objects. Always we can create new relations through BMIDE under ImanRelation business object. ImanRelation B.O Steps to create new relation Open BMIDE and load the custom template. Search for ImanRelation in Business object tab. Right click ImanRelation -> New Business Object. Type in the Name (real name) and Display Name (This name will be shown to end user for pseudo folder name). Relation creation window

Teamcenter custom handler build in BMIDE

In this blog we can see how to register and build a custom handler through BMIDE. Please refer my previous blog Setting up BMIDE for coding and building DLL to set up BMIDE for coding. Register Custom Handler Make sure you have a active library defined in Extensions\Code Generation folders. If you need a new library for managing handlers, create a new library and make it as active library. Create a custom extension rule. Open the Extensions\Rules folders, right-click the Extensions folder, and choose New Extension Definition. In Extension dialog box, along with Name of the extension and click the Add button to the right of Availability table. Select the business object as Session, Business object as Type, Operation as BMF_SESSION_register_epm_handlers and Extension Point as BaseAction. Extension availability Click Finish Extension view Add your custom extension as a base action on the BMF_SESSION_register_epm_handlers operation. Open the Session business object and click the Oper

Setting up BMIDE for coding and building DLL

Coding can be done either in external coding platforms like visual studio or using Teamcenter BMIDE application. Siemens suggests BMIDE for coding the server side customization. In this blog, let us see how to set up BMIDE for coding. Set up a Business Modeler IDE project for coding Modify BMIDE.bat file When you install or configure the Business Modeler IDE, set up the JDK location and a compiler application. The bmide.bat file starts the Business Modeler IDE. Set the location of the JDK in the install-location\bmide\client\bmide.bat file. set JRE_HOME=C:\Program Files (x86)\Java\jrex set JAVA_HOME=C:\Program Files (x86)\Java\jdkx.x.x set JDK_HOME=C:\Program Files (x86)\Java\jdkx.x.x Set TC_ROOT variable to Teamcenter installation path. if not defined TC_ROOT set TC_ROOT=C:\Apps\Teamcenter12\TC_ROOT On Windows when Microsoft Visual Studio is used for compiling, a call to the vcvarsall.bat file in the bmide.bat file is required. The call should be before the PATH statement. Add Visua

Teamcenter Batch LOV

Teamcenter offers 3 types of LOV and based on the use case, choose the LOV type. Unlike Classic and Dynamic LOVs, Batch LOVs are managed externally. To update or remove values from Classic or Dynamic LOV, we need to update LOV via BMIDE and deploy the changes as templates using tem.bat. Where as in Batch LOV, the updates happen using utility and does not require system downtime. Initially Batch LOV should be created in BMIDE and added to the respective property or properties. Once you deploy the batch lov to the database via tem, you can subsequently add values to the LOV using xml and load it into Teamcenter using bmide_manage_batch_lovs utility. To update existing Batch LOVs, you can extract the existing LOV values through the same utility in XML format, update the xml files and load it back using same utility. Creating new Batch LOV 1. In BMIDE, open Extensions\LOV Folder. Right click Batch LOV folder and choose New Batch LOV. Batch LOV 2. Click Finish 3. Add the Batch LOV to th

Teamcenter: Basics of Report Builder

Teamcenter Report builder module allows to create custom reports based on PLM data from Teamcenter. Teamcenter Reports are mainly based on queries and PLMXML framework. Report definition specifies the data to display in the report. This includes the data source, additional properties to be extracted, and the rules for importing the data. XSL style sheets allow to control the properties you want to display in the report and the display order. They also help to define the look and format of the report. Report Administrators (DBA or non-DBA users) creates and manages the report definitions. End users uses these report definitions to generate various types of reports in Teamcenter or Active Workspace. Optional Teamcenter Reporting and Analytics( TcRA ) standalone application is used to create advanced reports using various data sources. Types of Reports Summary Reports Summary reports present information based on a Teamcenter saved query definition. No object selection is requi

Types of Property in Teamcenter

Properties contains information describing the business object like name, description and so on. For Example, A screw object can contain properties like name, description, length, diameter, material, etc. A business object derive its properties from its persistent storage class. In addition to the persistent properties from storage class, business object can also have additional properties like run-time properties, compound properties and relation properties. Properties shown for business object in Rich client Types of Properties Persistent Persistent properties are properties of business objects that remain constant on the object. A simple value (for example, integer, string, or date). The value is stored in the database as an attribute and mapped to the property. Run-time A property that is defined at run time and attached to types. Run-time properties are derived each time the property is displayed. Run-time properties do not map directly to persistent attributes, references,

Basics of Teamcenter Query Builder

Query Builder application in Teamcenter allows you to create customized searches for objects in both local and remote Teamcenter databases. Basics of Query Builder Teamcenter Query is based on Teamcenter persistence data model. Refer Teamcenter Data Model Layer section to understand Teamcenter data model Query is created against any of the Teamcenter persistence class. Query criteria can be defined either on attribute of target object or for the related object which are related to search class through either GRM relation or reference. Referenced-by clauses allows creating query based on reversed-reference relationship. For example, query to find dataset objects that are referenced, through an IMAN_specification relationship, by an item revision with a specific name. Query hints assist user to navigate the schema by presenting a relationship to traverse and the steps required to build the relationships into query definition. For example, item to item-master form. Criteria can be mad

Teamcenter Preferences

Teamcenter preferences are settings stored in the Teamcenter database that provide a mechanism to control and define Teamcenter behavior by letting you modify the interface, set default behavior, and specify default values. Use Teamcenter preferences to configure many aspects of a session of application behavior, such as how assemblies are revised, whether extension rules are bypassed for specified operations, and which Teamcenter objects are displayed in integrations. Each application may have associated preferences. They are similar to environment variables, except that they operate with several layers of permissions

Teamcenter Item Business Object (Item Data Model)

Items are the fundamental object used to model data in Teamcenter. They are commonly used to identify an element of a product (component, assembly, end item) or other data such as procurement specification, test procedure, standard part, shop tooling, change, and so on. Data modeled using the Item business object is generally revision controlled data and all revisions of the information must be maintained, tracked, and recoverable. Data must also be modeled using the Teamcenter concept of item if you want to build a structure of the items such as a bill of material (BOM) for items that represent a product. Item is the most common business object under which you create a new business object. Use the Item business object or its children when you want to create business objects to represent product parts. When you create a business object using Item (or one of its children) as the parent, in addition to the new business object, system also create an item master form, an item revision, and
