Updating Attributes of Process Plan
To update the attributes of an existing Process Plan object or its subtype, you must first check out the object. Similarly, you can also update the attributes of an existing Standard Procedure object or its subtype.
If you perform Undo Checkout on the Process Plan object, the changes are rolled back. When you update the Process Plan object, the version of the Process Plan object will be iterated upon checking it in. You can specify the OID of any iteration/revision/view of the Process Plan object or its subtype. You can update modeled and all other types of attributes, including IBAs such as enumerated lists.
To update an attribute, you must specify the value with its valid internal name. If a constraint is applied to the attribute, you must specify the internal name of the value specified in the constraint.
If you want to clear the value of an attribute, you can specify its value as null in the request.
If you do not specify an attribute in the request body, then the attribute retains its existing value.
* 
You cannot modify the following attributes: Name, Number, Standard, Category, Unit, Occurrence Allocation From Any Level.

"Process Plans": [
{
"ID": "OR:com.ptc.windchill.mpml.processplan.MPMProcessPlan:44148884",
"ProcessPlanQuantity": 2,
"Description": "Updated_Process_Plan1",
"CustomAttribute": "UpdatedTest1",

Request Headers
Content-Type: application/json
CSRF_NONCE: <Use the value from Fetch NONCE example>
Request Body
{
"ProcessPlans": [
{
"ID": "OR:com.ptc.windchill.mpml.processplan.MPMProcessPlan:200061",
"Description": "Description1",
"ResultedByObjects@odata.bind": [
"ChangeTasks('VR:wt.change2.WTChangeActivity2:205227')"
]
},
{
"ID": "OR:com.ptc.windchill.mpml.processplan.MPMProcessPlan:200465",
"Description": "Description2",
"ResultedByObjects@odata.bind": [
