Parts and Part Revisioning
Parts:
Part objects in ION represent abstractions that carry information about a particular part, while the physical parts themselves are part inventory objects. The part objects dictate the MBOM, revision, supplier part number, tracking type and other additional attributes about a part.
Below is a list of part attributes and their description. For a more complete list of part fields use the graphiql editor to view the part object.
Part Object | Description |
id | Unique identifier of Part object |
partNumber | parts must have a unique partNumber and revision |
revision | Revision for part, defaults to A |
trackingType | If set enforces all inventory for part to match tracking type. Can be either "serial" or "lot" |
quantity | The summed quantity of all inventory for a part |
partsInventory | List of inventory objects related to a part |
runs | List of runs related to part |
mbom | List of MBOM item which describe the BOM of a part |
Query Parts
The queries below specify how to list parts by a filter or get a specific part.
Create Part
Creates a part object with a particular part number. Part number and revision must be unique, if no revision is supplied in the create mutation then the part defaults to revision A. Once created the revision of a part cannot be updated, instead the createPartRevision mutation must be used to iterate a part's revision. Returns the new part.
Mutation to create part object
Update Part
Updates a part object. Tracking type can only be updated to either "serial" or "lot" if all existing inventory objects related to this part conform to the new tracking type. Returns the updated part object.
Mutation to update part object
Create Part Revision
Creates a new revision for a particular part. A revision can be generated from any part, there are no restrictions requiring the revision to be generated from the current latest revision. For example if our part "ion-13" has existing revisions A and B, then a third revision C can be generated from either existing revision A or B. All information in the new revision is copied over from the old revision unless explicitly overriden in the mutation input. The new revision will be the next valid alphabetic character from the part's latest revision. If the part's latest revision is C, then the new revision will be D. If the part's latest revision is Z, then the new revision will be AA. Returns the newly created part object with the updated revision.
Mutation to create a part revision
Delete Part
Delete a part object. This will delete not only the part object itself but also cascade and delete the MBOM and MBOM substitutes associated with this part. A part which has existing inventory or was used within a run cannot be deleted. Returns the ID of the deleted part.
Mutation to delete part object
Query to retrieve parts
Custom Part Revision Scheme
ION allows users to define custom schemes for part revisioning. These schemes are defined within an organization's settings, the mutation below demonstrates how to create a new scheme. First a user needs the ID and etag of the organization before its settings can be updated. Following that there are four additional variables which define a part revision scheme.
name (string): The name of the new revision scheme
default (boolean): If true all newly created parts will inherit this revision scheme
allowOverflow (boolean): Defines whether an error should be raised when the max iteration of a revision scheme is reached, or if it should overflow to the next available value.
format (array[string]): The format is an array of strings which defines how the values of a revision scheme should appear. The string values in the array can be either
NUMERIC
,ALPHABETICAL
, or single character length constants. The format below would define part revisions like00-1
or95-7
.
Update Part Revision Scheme
Once a part revision scheme exists in an organization's settings it can subsequently be updated. Currently the only allowable updates to a part revision scheme are the fields allowOverflow and default.
Converting the Revision Scheme of an Existing Part
There are two strategies for changing the revision scheme of an existing part. Both involve setting the revisionScheme
for a part in either the updatePart
or createPartRevision
mutations above. The revisionScheme
should be set to the name of one of the schemes in the organization's settings.
Setting the
revisionScheme
in theupdatePart
mutation casts the part's revision. For example if a part currently has revisionD
and we update that part to use the revisionScheme "new scheme" which we created above then the revision will be set to00-4
Setting the
revisionScheme
in thecreatePartRevision
mutation resets the parts revision, starting it over from the initial revision of the new scheme. If a part has revisionD
and we update the part'srevisionScheme
in thecreatePartRevision
mutation it will be set to00-1
.
