ZBUS2032 not shown in workflow and status in SWEL- no receiver entered

I am trying to change an existing workflow(This one has the standard BO- BUS2032 linked). Now I am trying to link the same workflow to a custom BO(ZBUS2032) copied from BUS2032. This custom BO is generated, released, delegated. I have maintained the default values as

Method = DISPLAY and

Attribute = SALESDOCUMENT

Created an entry in SWE2 for ZWBUS2032 with

Object type = ZWBUS2032

EVENT = CREATED

RECEIVER = WS90000014

Receiver call = FM

Receiver FM = SWW_WI_CREATE_VIA_EVENT

checked the linkage activated checkbox and left the rest AS-IS

In the workflow side,

In the task screen- I added the task number that has (ZBUS2032 and the new method), specified the triggering events and binded, event is green. When I click on Define binding autom. it shows

WIOBJECT_ID = &ZBUS203&

In the actual event

I added the Object type to ZBUS2032 and the event as CREATED, clicked on start condition and specified the SALES document type condition but it doesn't go green.

When I click on the binding, on the right hand side of the new window where the workflow parameters are there, it still shows BUS2032 instead of ZBUS2032

No errors, I activated. When I hit the test, it still shows BUS2032.

When I do the process through front end and check SWEL, it says No receiver entered.

I am new to Workflow. Kindly please advice.
