Hi Masa,
When I gone through the error log for Approve Purchase Requisition, I am getting error "Backend error occured. T100 Info:GBAPP_APV_MSG-013".
When, I checked with URL http://xxx:8000/sap/opu/odata/sap/gbapp_prapproval;mo/LaunchPageCollectionfrom network element in NW Gateway client, getting below error
<?xml version="1.0" encoding="utf-8" ?>
-<error xmlns="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata">
<code>GBAPP_APV_MSG/013</code>
<message xml:lang="en">Workflow Task Type is not passed as filter criteria</message>

<SAP_Transaction>Run transaction /IWFND/ERROR_LOG on SAP NW Gateway hub system and search for entries with the timestamp above for more details</SAP_Transaction>
<SAP_Note>See SAP Note 1797736 for error analysis (https://service.sap.com/sap/support/notes/1797736)</SAP_Note>

But, when I checked in NW gateway client with the below URL, I am able to see the PR for approval in user inbox.
