Bills of Material: BoM Changes Log

Parent

The part number of the assembly parent.

Component

The part number of the component being changed. If there are multiple entries of the same component in the assembly, the system will not distinguish between them.

Change type

This is a numeric code that identifies the type of BoM maintenance transaction that resulted in the log record. In the displayed list and on standard reports this code is used to provide descriptors. It contains one of the following codes:
1 = Component additions to the assembly
2 = Component deletion from the assembly
3 = Component quantity change during edit
4 = Component engineering issue change without quantity change

NOTE: Type 4 changes ONLY apply to the change of engineering issue reference recorded against the component in the bill of materials file. It does NOT apply to a change of the part’s engineering issue in the part master record, unless accompanied by an “Update Issue…” which includes the use of the part as a component for the parent in question.

Change quantity

The quantity of increase that has been made to the BoM quantity for the component’s use in the assembly. If negative, there has been a reduction in it’s use. Zero quantity will only apply to type 4 changes of issue only.

Parent engineering issue

For quantity changes, this shows the parent part’s engineering issue reference at the time the change took place. This is the part master record engineering reference for the parent part. For issue only changes, the component issue as now referenced in the parent part’s linked BoM record is shown in this field.

WARNING: If you are using Engineering Issue control to manage engineering change, you should always make sure that you change the parent part’s engineering issue reference in Part Maintenance before you carry out any BoM maintenance or component part Update Issue. This will ensure that the Changes Log will reflect the fact that changes relate to the new issue of the parent. If you do it after BoM changes, the parent issue field in the Changes Log will indicate that the changes related to the old issue.

BoM component engineering issue

The bill of materials component engineering issue reference after the change took place. This is not necessarily the component part’s engineering issue in the part master record. It is changed either in BoM maintenance or during “Update Issue…” in parts maintenance (see also the warning above).

Date and time

The terminal date and time when the change was recorded. This is a single combined field of both date and time.

User ID

The Transaction ID of the user who made the BoM change that was recorded.
