According to the documentation , the Parent Endpoint is only applicable for operations of type aggregation and get object.
but …
It is possible to call a webservice endpoint from both the Web Service Before Operation Rule and Web Service After Operation Rule. For both you have all the info of the Operation, like requestEndPoint, etc.
Thank you Remold, if I were to call more than 2 endpoints in the before/after rule there will be overhead of handling exceptions/audit and parsing the responses right?
If I were in this situation I would do the create and in the after operation rule schedule a new workflow to process the remainder steps. For instance create a new modify plan and call the LCM Provisioning workflow (which will again use the Web Services connector with the Update Account Endpoint).
