• Teamcenter Validation to Edit Structure Lines

Tools –> Validate Occurrence(manual validation)

Administrator can configure Teamcenter to set rules for what kind of contents are allowed in structure line .Any violation of this business rule will not add the invalid component to structure line or edit the structure line.

Validations are run automatically while creating structure, although it can be done manually (for existing structure or property update) by clicking the menu button for Validate Occurrence.

Validations & Restrictions can be summarized as below:

Restriction on Contents		Validation for Operations
Only certain Item types or classes may: Exist anywhere in structure Be children of others Be parents of others Properties of parent or child object should be specified or be NULL		Creating New Occurrence Adding Substitute for given occurrence Cloning a structure Importing or Exporting Structure Revise or Baseline

• Edits to Structure

  • Adding Components

    • Copy & Paste Objects

Copying or cutting a structure line, makes it available in the clipboard .These lines can be pasted to selected structure line through Paste or Paste Special.

Item and item revisions (including parts and design), structure lines, item elements are allowed to be pasted in structure manager .

Edit–> Copy, or Copy and Edit–> Paste or Paste can also be used for Item & Item Revision(Including design and parts).

Effect of Copy Paste :

Quantity and Notes	Copied & Pasted
Find Number	Not Copied & Pasted
Associated Substitute List	Copied & Pasted
Variant Condition	Not Copied & Pasted

• • • Quick Add

Existing component can be added in the structure directly by entering the ID .Text Box is clicked on lower left of structure manager .Enter the component id and click on to add it in selected assembly.

• • • Add Component to assembly

If while adding components to structure more information needs to entered, Edit–> Add… should be used.

Following data can be entered in the opened Add dialog box:

1. Component ID to be added– ID is either entered or searched -If the same Id is shared by different object type, Select Unique Item dialog is opened inside Add dialog. Select the component from this dialog.
2. Revision for precise assembly.
3. View Type(Comes as useful when copying component with multiple view types)
4. Component or Selected Assembly can be chosen.
5. Substitute components can be defined.
6. Number of Occurrence
7. Quantity per Occurrence
8. Find Number

• • Create New Item/Revision

With write access to BOM View Revision, top-down modeling can be done by creating item/part and adding it in structure at the same time. Selecting parent assembly and choosing File New Item or File New Part will open Create Item or Create Part Dialog box respectively. Entering the required fields item/part/revision can be created and added as component under selected assembly.

• • Paste Special to paste a component

Additional data can be specified for the use of component through Paste Special. In the Paste Special Dialog box component ID(Revision) and name information is prepopulated from component in clipboard.

• Restructuring Structure

Restructuring edits the manufacturing product structure .This is disabled for structure with CAD designs. Restructuring preserves derived occurrence structure and data related to it. (Depth levels move up or down, parents change, but structure remains same.)Following are encountered with restructuring operation.

Incremental change	Integrity maintained
Variants (classic & modular)	Integrity maintained
Structure Relationship	Integrity maintained
Pending Edits for Structure	Must be saved before restructuring
Absolute Occurrence attributes& data	Teamcenter displays warnings

Restructuring actions include:

• • Removing/Inserting level

Edit –>Insert Level

Inserts the new item one level up the selected lines with quantity 1.This means selected lines becomes children of newly inserted item. Original parent becomes the branch of newly inserted item. All the selected line should share the same parent originally before insertion. All existing variant conditio ,notes ,absolute occurrence and other data of selected lines is moved down with it. Let’s say new item inserted is X

Before Insertion

After Insertion when C, D & E were selected

Edit –>Remove Or Remove

Selected line is removed and its children reattached to one level up parent line, if ‘Keep Subtree’ option is selected. Any Option of the removed line is moved up and its variant condition is merged.

Any pending edits on line with red strikethrough should be reverted before this action.

• • Moving a node

Cut and Paste the node to selected line to move the node. All substructure and occurrence data moves with the node.

Following actions can be performed at the time of pasting.

• • Item ID and Revision ID can be changed
  • View type can be changed ,if applicable

Any pending edits on line with red strikethrough should be reverted before this action.

• • Splitting Occurrence

A line representing several occurrences and having quantity value more than one can be split in two branches with Edit Split Occurrence. Both the branches will initially have same variant condition, notes and other data which can be modified independently.

• • Replacing Node

Edit –>Replace Node or

An item representing the node can be replaced with a different item preserving all data associated with the original node

• Adding Parts to NX

Parts to be added to NX can be:

• • Individual parts
  • Parts in context of assembly

They can be copied to Teamcenter clipboard and with right click and selecting Send clipboard content to NX, they can be sent to NX clipboard .Only revisions are sent to NX.

With NX paste options ,parts are pasted in the assembly .Individual parts are pasted at default location and parts in context of assembly i.e. structure lines are pasted based on the positioning information it has from Teamcenter .This means parts will position correctly for any other selected level in NX assembly, according to its spatial information.

• Editing Quantity-Unit of Measures

Unit of Measures is an attribute of an item .Quantity property of structure line is specified based on unit of measure of item .For example if unit of measure is KG , quantity can be specified as 1.8 .UOM can also be specified as each ,which will take numerical whole number in quantity field. UOM for item type can be specified and cannot be edited once it is used in structure or when item revision is released.

Fnd0PSEQtyConversionDSName and Fnd0PSEEnableQtyConversionUOM Business Modeler IDE constants can set user-defined UOM.

In Structure Manager, Edit Quantity Dialog pops up on double clicking quantity property .Here quantity can be defined in user selected UOM .Say when item default UOM is KG, user can enter 500 and UOM as gram and click on OK .This value is automatically converted and updated as 0.5 KG. In database ,quantity is stored in default UOM for item type.

• Editing BOM View Revision-Save As

File–> Save As BOM View Revision

BOM View Revision stores the occurrences of single level assembly .It is generally created automatically when adding first component to an assembly .But sometime, it may be required to create or copy BOM View Revision separately when certain other view type is required of similar structure. BOM View Revision may also need to be copied, when we need to copy structure to another item.

This action of Save As will copy occurrence attributes, including the find number, notes, quantity, substitutes, and variant conditions (modular) into the new BOM view revision.
