Hi,

I have a scenario where Entity A need to me linked to Entity B and it is one to many relationship. i.e one record in Entity A can have a relationship with n records in Entity B.
But I want to retrieve records from Entity B based on priority.

I want to retrieve A to B with B age as 20, if I don't find 20 I'll go with 30 and so on. 

Entity A
S.no
A1
A2

  Entity B  
Key Name Age
A1 X 20
A1 Y 30
A1 Z 40
A2 L 30
A2 M 40

From the above tables I want 
A1-X

A2-L

    I suggest you download xrmtoolbox and use FetchXML builder for this.

    Below is fetchxml based on the fields that you given.

    <fetch>
      <entity name='Entity A' >
        <attribute name='S.no' />
        <link-entity name='Entity B' from='Key' to='S.no' link-type='inner' >
          <attribute name='Name' />
          <filter type='or' >
            <condition attribute='Age' operator='eq' value='20' />

            <condition attribute='Age' operator='eq' value='30' />
          </filter>
        </link-entity>
      </entity>
    </fetch>

    please mark as verified if this answers your question.

    Or the other way around is making the code dynamic:

    <fetch>

     <entity name='Entity A' >

       <attribute name='S.no' />

       <link-entity name='Entity B' from='Key' to='S.no' link-type='inner' >

         <attribute name='Name' />

         <attribute name='Age' />

         <filter type='or' >

           <condition attribute='Age' operator="ge" value='20' />

         </filter>

       </link-entity>

     </entity>

    </fetch>

    Then on your code, you will get the Age attribute and doing your things (e.g check Age = 20, 30,.. etc).

    Thanks Tyler,

    I tried in this way but I'm getting both the records.

    Like A1-X

          A1-Y

    Thanks Temmy,

    I tried in that way but I'm getting two records like

    A1-X

    A-Y

    And I just gave age as an example but in my scenario Age is String not a number.
