Regarding RFC Function module in Multimapping

Question

Hi All
I am trying to use RFC function module in Multimapping at target side.I want to call RFC Function based on some condition, if condition fails i dont want to call the Function Module. So i need to change the occurance of target RFC Message to 0...1 When
i try to change occurance in messages tab, it is displaying message that RFC Function module not found. When i change 
occurance to 1..1, then it is showing RFC structure in mapping properly. I am suspecting why it is behaving like this.
Can we use RFC Function Module in Multimapping??. Please share ur experience on this.
Thanks,
Balu

Hi,
  Can any body cofirm how below sender message will behave in Interface Determination,
<?xml version="1.0" encoding="UTF-8"?>
<ns0:MT_FILE1 xmlns:ns0="http://ctrlanddataconceptsinglereceiver">
<Structure>  
<***>male</***>
   <ID>12</ID>
   <Desig>cons</Desig>
   <Sal>1000</Sal>
</Structure>
<Structure>  
<***>female</***>
   <ID>12</ID>
   <Desig>cons</Desig>
   <Sal>1000</Sal>
</Structure>
</ns0:MT_FILE1>
In my interface determination, i will add 2 inbound interfaces and two mappings.
For first interface i will check condition like if Structure/***=male then it has to goto one receiver agreement
For second interface i will check condition like if Structure/***=female, then it has to goto another receiver agreement.    
But in my sender payload *** is male and female also. Will it execute 2 receiver agreements???.
My openion is it will go through 2 interface mappings and it will execute 2 receiver agreements.
Thanks,
Balu.
