Validate effectivity of modified source BOM elements in target BOM

You can collect all equivalents of a part in a source BOM, such as an EBOM, that is reused or assigned multiple times in a target BOM, such as an MBOM, and thereby verify that all units for those equivalents have a single valid effectivity assignment in the MBOM.

Example

A part or assembly on the left side of an aircraft might have a part identifier such as FRAME1-1 that includes the base part name FRAME and number FRAME1-1. When a design change occurs, engineering might then use an equivalent assignment scope to change the identifier to FRAME1-2. This can also apply to assemblies of parts.

Procedure

1. Open a work package that contains an EBOM with modified parts or assemblies and a manufacturing bill of materials (MBOM) that uses those modified elements from that MBOM.

2. In the EBOM, select a modified part or assembly assigned to the MBOM.

3. Select the MBOM assembly to which you want to assign the modified part or assembly subassembly, click Add → Add Child, and create a new manufacturing container subassembly to be used to assign the equivalently assigned part or assembly from the EBOM.

4. From the EBOM, select the equivalently assigned part or assembly, and from the MBOM, selects the new manufacturing container subassembly, and then click Assign .

If there is no effectivity definition for the parts, any parts commonly reused across EBOM subassemblies inherit occurrence effectivities based upon net effectivity; the effectivity for the parts in the lowest subassembly inherits the effectivity of the next highest, and upward through the chain to the highest parent with defined effectivity. The same applies to parts in the MBOM.

5. To collect all equivalents of a part in the EBOM and MBOM and verify that all units for those equivalents have a single valid assignment in the MBOM, in the EBOM toolbar, the engineer clicks Validate Effectivity Coverage .

A bar chart in the Validate Effectivity Coverage dialog box is displayed. EBOM Range shows the total effectivity for a specific part in the EBOM per unit. The lower bars display the effectivity for each occurrence in the MBOM. To change the end item, from the End Item list, select a preferred end item.

6. Drag the start and end points of each MBOM occurrence to modify its unit effectivity range, and then click Save.
