Missing node in Message Mapping when test mapping??

Question

Experts,
I have the following Mapping Structures:
Sender:
<Recordset> 1-1
   <Records> 1:unbounded
        <field1>1:1
        <field2>1:1
Receiver:
<Recordset> 1-1
    <Header> 1-1
     <Records> 0-unbounded
           <field1>
           < field2>
     <Trailer> 1-1
Mapping is completed for  all fields here.But one thing I notice is on Receiver side : all nodes are Green exept Records - it is Gray with some red smal dot in the gray..
1.Question: What this means?Shouldn't all nodes turn green after mapping is done??
2.When click on TEST on Message MApping I dont even see the Receiver Records node appearing on right(receiver side) But I was able to see Header and Trailer...Why the Records is missing??
On the other hand the result from the test is successfull which is even more confusing ,How come it can be succesful since Records is not there...
I can provide screenshots if needed for more clarity ..Any help is appreciated asap..Thanks much to all!

Hi John,
   It is very simple and there is no complexity with this problem.
  <b> 1.Question: What this means?Shouldn't all nodes turn green after mapping is done??</b>
        If you mapped the source field to the correspoding target field..all the target fields get turn to green color. If you didn't mapp any target field that filed should appear with gray color..comming to the small circle in the recordset field...it is indicates that ..that field is "Unbounded".
   For resolving the above issue...do the mapping like this.
   <Recordset>---><Recordset>
   <Records>-------><Records>
   <field1>----><field1>
   <field2>-----> <field2>1
Keep the empty constant value for the target field Header...
   empty constatnt---->Header.
So once you done this check the mappping it will execute fine and even you able to see the recods node in the target structure.
  Please let me know if you have any queries...!
Thanks and Regards,
