I'm configuring Work Execution. The Work Order History query that is called when retrieving past work orders for assets or locations is open-ended. Consequently, several thousand rows are retrieved each time and the application times out. I can attach where clause (see below) to limit it to records with actfinish after a specific date. However, what I want to do is something like this...
spi_wm:actfinish>now()-30
<!--WorkOrder History Asset Resource-->
<resource id="workOrderHistoryAssetLoc" class="application.business.WorkOrderObject" defaultOrderBy="wonum asc" describedBy="http://jazz.net/ns/ism/work/smarter_physical_infrastructure#WorkOrder" name="workOrderHistoryAssetLoc" pageSize="50" providedBy="/oslc/sp/WorkManagement">
<attributes id="workOrderHistoryAsset_attributes1">
<attribute describedByProperty="dcterms:identifier" id="workOrderHistoryAsset_identifier_dctermsidentifier1" index="true" name="identifier"/>
<attribute describedByProperty="oslc:shortTitle" id="workOrderHistoryAsset_wonum_oslcshortTitle1" index="true" name="wonum"/>
<attribute describedByProperty="dcterms:title" id="workOrderHistoryAsset_description_dctermstitle1" index="true" method="descriptionChanged" name="description"/>
<attribute describedByProperty="spi:status" id="workOrderHistoryAsset_status_spistatus" index="true" method="statusChanged" name="status"/>
<localAttribute dataType="string" id="workOrderHistoryAsset_statusdesc_string" name="statusdesc"/>
</attributes>
<queryBases id="workOrderHistoryAsset_queryBasesh">
<queryBase defaultForSearch="true" id="workOrderHistoryAsset_queryBase_searchAllWorkOrdersh" name="searchAllWorkOrdersAsset" queryUri="/oslc/os/oslcwodetail?savedQuery=getWithComplexQuery"/>
<!-- TODO AWH 20170130 - add where clause to this query -->
</queryBases>
<whereClause clause="spi:status in ['COMP','CLOSE'] and spi_wm:actfinish>'2016-10-10T09:50:00-04:00'" id="workOrderHistoryAssetLoc_whereClause"/>
</resource>
I see elsewhere where there are formulas in the app.xml but I don't know what types of operators or language is available to accomplish something like this. I was hoping the whereClause attribute had the ability to use a resolverClass and resolverFunction so that I could replace a named parameter with a value derived from a javascript function... no dice. Any help would be appreciated!
