Receiver Type Function Module in SWE2 use of export parameter.

i am trying to understand the underlying concept in following things:(neednot to say i have searched alot and read sap documentation already).

In event type linkage table say i have an entry for BOR -> AFVC_PM.

As per sap Documentation says all these FM will trigger in following way.

1 Check Function Module (to place any validations/checks)

2 Receiver Type Function Module ()

3 Receiver Function Module.

Thats fine.

This is what documentation says about Receiver Type FM(2nd FM) not Receiver FM(3rd FM).

This FM has 1 export paramter

Export parameters

RECTYPE type SWETYPECOU-RECTYPE Receiver type( Result of the evaluation by the receiver type function module.)

if i am understanding this right, in this FM receiver type will be decided .

i have placed BREAK-POINT in this FM  and passing value WS90000024 (Workflow with simple mail step) in export parameter RECTYPE.

after everything executed successfully why i can't see that mail in my inbox.

Please correct me if i had misunderstood the concept .
