Use a new variable as Observable and not method which return a Observable. Then just subscribe to that variable. Try this:
public workitemTemp: BehaviorSubject<any> = new BehaviorSubject(null);
public WorkItemTempObj= this.workitemTemp.asObservable();
setWorkitemTemp(value: any) {
this.workitemTemp.next(value);
}
this._sharingService.getWorkItemTempObj.subscribe(res => {
if (res != null) {
this.showEnvelope(res)
}
});
