Navigating to Pending Effectivities on Raw Material Links for a Made From Set
You can retrieve the Raw Material Links (Made From Links) for a specific Made From Set object using expand on MadeFromLink navigation.
To retrieve information for single or multiple pending effectivities (Date, Lot, Unit, or Serial) associated with the Raw Material Links for the specified Made From Set object, you can further expand with the PendingEffectivities navigation.
The request also returns a Change Management-specific canonical link for the pending effectivity object for the Accept Header specified as
Accept: application/json;odata.metadata=full
You can click the canonical link to navigate to the specific pending effectivity associated with a Raw Material Link.
For multiple pending effectivities on a Made From Link, the request returns a canonical link for each of the effectivities, in the response.
* 
Pending effectivities returned with expand do not show the range sets as it is a limited representation of the entities. To get full information about pending effectivity entities, you are required to click the canonical links returned in the response.
This example shows you how to retrieve a pending date effectivity associated with a Raw Material Link for a specific Made From Set. Use the following GET URI and Accept Header.
URI
GET /Windchill/servlet/odata/BomTransformation/MadeFromSets('OR:wt.part.WTPart:198649')/MadeFromLink?$expand=PendingEffectivities
Request Headers
Accept: application/json;odata.metadata=full
Content-Type: application/json
The response includes a canonical link to the specific pending date effectivity associated with a Raw Material Link, for example,
"href": "http://vagrant.ptcnet.ptc.com:2280/Windchill/servlet/odata/v6/ChangeMgmt/PendingEffectivities('OR:wt.eff.PendingDateEffectivity:246688')"
When you click the canonical link, you can retrieve information for the pending date effectivity along with the CreatedOn, ID, and LastModified attributes.
