Requirement
- Manage Requirement Usages
-
This option allows you to activate a usage specification when a
requirement is assigned to an item or an operation. The list of
possible values for the usage is defined by the customer thanks
to a CATRule file, DELPPRRequirementUsages.CATRule, located in
the ..\resources\knowledge\scripts folder. The
standard CATRule defines the Realize and
Control values.
 By default, this option is not selected.
- Include an Ignore Usage
- This option is available only if the Manage Requirement Usages
option is selected. This option adds an
Ignore usage to the
Realize and
Control values.
By default, this option is not selected.
Assignable Requirements for an Item - Assembly
- Get Requirements from Engineering Items Linked to Selected Item
- When selected, this option computes the list of possible assembly
requirements as follows:
- It retrieves the engineering item scoped by the selected
manufactured item.
- If there is no engineering item found, then it obtains the
engineering items that are the assignment filter's direct
targets on the selected manufactured item.
- If there are no engineering items by scope or by assignment
filter on the selected manufactured item, then it obtains
the engineering items from the first upper scope or the
first upper assignment filter respectively.
Note:
The parent
of the selected manufactured item is checked recursively
for scopes and assignment filters.
- From the retrieved engineering item, it obtains the published
requirement specifications and all the requirements thereafter.
By default, this option is selected.
- Get Requirements from Children of Linked Engineering Items
- It retrieves all the children of the previously identified
engineering items and obtains the requirement specifications linked
to the identified engineering item and all the requirements
thereafter.
-
Note:
When selected for assemblies, this option displays the
Display Requirements from lower
scopes check box in the Requirement
to Item Assignment
 tab. Select this check box to obtain requirements below the
lower scope.
-
By default, this option is not selected.
- Get Requirements from Resulting Product Defined on Selected Item
- If a Resulting Product is defined on the selected manufactured item,
then it retrieves the requirement specifications published by the
Resulting Product root and all FTA requirements thereafter.
By default, this option is selected.
- Requirements from Global Specification Link
- When selected, this option computes the list of possible assembly
requirements as follows:
- It retrieves all the requirement specifications linked with
a Global Specification link to the selected manufactured
item and lists all the requirements thereafter.
- If there are no requirement specifications linked with a
Global Specification link to the selected manufactured item,
then it retrieves all the requirement specifications linked
with a Global Specification link to the first upper parent
scope and lists all the requirements thereafter.
-
By default, this option is not selected.
Assignable Requirements for an Item - Part Fabrication
- Get Requirements from Engineering Items Linked to Selected Item
- When selected, this option computes the list of possible individual
item requirements as follows:
- It retrieves the engineering item scoped by the selected
manufactured item.
- If there is no engineering item scoped by the selected
manufactured item, then it obtains the engineering items
from the first upper scope or the first upper assignment
filter respectively.
Note:
The parent of the selected
manufactured item is checked recursively for scopes and
assignment filters.
- From the retrieved engineering item, it obtains the published
requirement specifications and all the requirements thereafter.
By default, this option is selected.
- Get Requirements from Resulting Product Defined on Selected Item
- If a Resulting Product is defined on the selected manufactured item,
then it retrieves the requirement specifications published by the
Resulting Product root and all FTA requirements thereafter.
By default, this option is selected.
- Get Requirements from Global Specification Link
- When selected, this option computes the list of possible individual
item requirements as follows:
- It retrieves all the requirement specifications linked with
a Global Specification link to the selected manufactured
item and lists all the requirements thereafter.
- If there are no requirement specifications linked with a
Global Specification link to the selected manufactured item,
then it retrieves all the requirement specifications linked
with a Global Specification link to the first upper parent
scope and lists all the requirements thereafter.
-
By default, this option is not selected.
Assignable Requirements for an Operation
- Get Assigned Requirements on First Upper Scoped Items
- When selected, this option computes the list of possible operation
requirements as follows:
- It retrieves the manufactured item from the first upper
scope.
- It retrieves all the assigned requirements to this
manufactured item scope.
- If there are requirement specifications linked with a
consumption link to this manufactured item scope, then it
also retrieves all the requirements thereafter.
-
By default, this option is selected.
- Get Requirements from Output Defined on Selected Operation
- If an operation output is defined on this operation, then it
retrieves the requirement specifications published by the operation
output root and all FTA requirements thereafter.
By default, this option is not selected.
- Get Requirements Assigned on Previous Operations
- When selected, this option computes the list of possible operation
requirements as follows:
- It retrieves the requirements assigned to the previous
operations.
- It retrieves the requirements defined on the output of these
operations (which are not visible to the next
operations).
-
By default, this option is not selected.
- Get Requirements from Global Specification Link
- It retrieves all the requirement specifications linked with a Global
Specification link to the first parent system or workplan and all
requirements thereafter.
By default, this option is not
selected.
