如何在基于 Fetchxml 的报告中的“或”过滤器中使用“in”运算符？

Question

I am using following xml in an Fetch based report in SSRS for Dynamics 365. I've allowed @transaction parameter to null but rest of the both parameters must have values. So, I put an or condition so that if @transaction is null or 0 then on the base of 1 and 2 grab the orders. I've total 10 records but they are not being shown or the report preivew show 0 records. Any idea how to resolve this?

    <fetch version="1.0" output-format="xml-platform" mapping="logical" distinct="false">
      <entity name="salesorder">
        <attribute name="salesorderid" />
        <attribute name="ordernumber" />
        <order attribute="ordernumber" descending="true" />
        <filter type="and">
          <condition attribute="new_transaction" operator="eq" value="@transaction" />
          <condition attribute="createdon" operator="on-or-before" value="@To" />
          <condition attribute="createdon" operator="on-or-after" value="@From" />
        </filter>
        <filter type="or">
            <condition attribute="new_transaction" operator="in" >
                <value>1</value>
                <value>2</value>
            </condition>
          </filter>
      </entity>
    </fetch>

Answer 1

If I understood correctly, you can replace your filter like below to get result.

<filter type="and">
   <condition attribute="createdon" operator="on-or-before" value="@To" />
   <condition attribute="createdon" operator="on-or-after" value="@From" />
   <filter type="or">    
        <condition attribute="new_transaction" operator="in" >
            <value>1</value>
            <value>2</value>
        </condition>
        <condition attribute="new_transaction" operator="eq" value="@transaction" />
   </filter>
</filter>

Pro tips:
1.Build the query in Advanced find, test the result & Download fetchxml from there to use in report.

2.If you write SQL query, transform it to fetchxml using Kingswaysoft sql2fetchxml free online converter.

3.Read this article to transform fetchxml into Adv find query.
