| # Reference Designators by Engineering Bom (tiedm2110m000) Use this session to to link reference designators to a EBOM line. You must start this session by selecting a EBOM line in the Engineering BOM (tiedm1110m000) session, and click Reference Designators by E-Bom on the toolbar, or on the appropriate menu. You must click New in this session to select reference designators. You can zoom in the Reference Designator field to the Reference Designators by Engineering Item (tiedm0120m000) session to select reference designators. If you did not already define reference designators by engineering item, you can zoom from the Reference Designators by Engineering Item (tiedm0120m000) session to the Reference Designators (tcmcs0190m000) session to select reference designators. A reference designator can apply to one or more items on the EBOM line. You must use the Quantity field in this session to indicate the number of items on the EBOM line to which the reference designator applies.

You can define multiple revisions of an engineering item. Typically, the most recent revisions are still in a design or test phase, another revision may have been taken into production, and older revisions are obsolete. A normal item can only become revision-controlled when it is copied from the Engineering Data Management module. Revision A version or revised version of an engineering item (E-item) or a revision-controlled item, that is, an item linked to an E-item. Several revisions of an E-item can exist. Example E-item: Mountain bike E-MB01
Revision | Description | Status
--- | --- | ---
A1 | Draft drawing of bike | Not released
A2 | Drawing of bike | Not released
A3 | Parent E-item of bike MB01 | Released
A4 | Obsolete bike | Canceled
Position The number of the EBOM line. Net Quantity The number of items on the EBOM line that is required to manufacture the end item. Reference Designator Indicates the location to insert a component on an item, for example, where to mount an electronic component on a Printed Circuit Board. Reference designators are often used in electronics, and can originate from a Computer-Aided Design (CAD) station. Related topics Overview of reference designators Description The description of the reference designator. This can be, for example, a code that expresses the location where you must mount a component item. Quantity The number of items on the EBOM line to which the reference designator applies. A reference designator can apply to one or more items on the EBOM line. Related topics Overview of reference designators Procedure for linking reference designators in the EBOM |
