Integrate SAP and InterSystems IRIS using OData

SAP offers a broad support to OData in all your products. So, OData can be an excellent option to exchange data between SAP and InterSystems IRIS.

1. Follow the instructions in the article https://community.intersystems.com/post/odata-and-intersystems-iris to expose your IRIS data as REST OData services.
2. To consume InterSystems IRIS data from SAP using OData, follow these steps (credits to the next steps of this tutorial: https://sapyard.com/sapui5-for-abapers-consuming-odata-service-from-sapui5-application-crud-operations/) :
3. Create a new SAPUI5 application by the name crud_demo.
4. Create a XML view ‘crud_demo.view’. Write below code in it.

<core:View xmlns:core="sap.ui.core" xmlns:mvc="sap.ui.core.mvc" xmlns="sap.m"
controllerName="crud_demo.crud_demo" xmlns:html="http://www.w3.org/1999/xhtml" xmlns:l="sap.ui.commons.layout">
<Page title="CRUD Operations">
<content>
<l:AbsoluteLayout width="10rem" height="10rem"></l:AbsoluteLayout>
<VBox xmlns="sap.m" id="vboxid"> 
<items> 
<HBox xmlns="sap.m"> 
<items> 
<l:AbsoluteLayout width="20px" height="20px"></l:AbsoluteLayout> 
<Button xmlns="sap.m" id="cbtn" press="oDataCall" text="Create"></Button>
<l:AbsoluteLayout width="20px" height="20px"></l:AbsoluteLayout>
<Button xmlns="sap.m" id="rbtn" press="oDataCall" text="Read"></Button>
<l:AbsoluteLayout width="20px" height="20px"></l:AbsoluteLayout>

</items>
</HBox>
<HBox xmlns="sap.m"> 
<items> 
<l:AbsoluteLayout width="20px" height="20px"></l:AbsoluteLayout>
<Input xmlns="sap.m" id="uniqueid" placeholder="ID" value="1"></Input>
<l:AbsoluteLayout width="20px" height="20px"></l:AbsoluteLayout>

<l:AbsoluteLayout width="20px" height="20px"></l:AbsoluteLayout>

<l:AbsoluteLayout width="20px" height="20px"></l:AbsoluteLayout>
<Input xmlns="sap.m" id="mobid" placeholder="Mobile" value="8888888888"></Input>
</items>
</HBox>
<HBox xmlns="sap.m"> 
<items> 
<l:AbsoluteLayout width="20px" height="20px"></l:AbsoluteLayout>
<Table xmlns="sap.m"
id="userdatatable" headerText="User Data"> 
<items>
<ListItemBase xmlns="sap.m" id="id1"></ListItemBase>
</items> 
<columns> <!-- sap.m.Column -->
<Column xmlns="sap.m"> <header> <Text xmlns="sap.m" text="Id" ></Text></header></Column>
<Column xmlns="sap.m"> <header> <Text xmlns="sap.m" text="Name" ></Text></header></Column>
<Column xmlns="sap.m"> <header> <Text xmlns="sap.m" text="Email" ></Text></header></Column>
<Column xmlns="sap.m"> <header> <Text xmlns="sap.m" text="Mobile" ></Text></header></Column>
</columns>
</Table>
</items>
</HBox> 
</items> <!-- sap.ui.core.Control -->
</VBox>
</content>
</Page>
</core:View>

4. Create crud_demo.controller.js. Write below code in it.

onInit: function() {
that = this;
// Create Model Instance of the oData service
var oModel = new sap.ui.model.odata.v2.ODataModel("/sap/opu/odata/sap/ZCRUD_DEMO_SRV");
sap.ui.getCore().setModel(oModel, "myModel");
},
oDataCall:function(oEvent)
{
// call oData service's function based on which button is clicked.
debugger;
var myModel = sap.ui.getCore().getModel("myModel");
myModel.setHeaders({
"X-Requested-With" : "X"
});
// CREATE******************
if ('Create' == oEvent.oSource.mProperties.text) {
var obj = {};
obj.id = that.getView().byId("uniqueid").getValue();
obj.name = that.getView().byId("nameid").getValue();
obj.email = that.getView().byId("emailid").getValue();
obj.mobile = that.getView().byId("mobid").getValue();
myModel.create('/userdataSet', obj, {
success : function(oData, oResponse) {
debugger;
alert('Record Created Successfully...');
},
error : function(err, oResponse) {
debugger;
alert('Error while creating record - '
.concat(err.response.statusText));
}
});
}
// READ******************
else if ('Read' == oEvent.oSource.mProperties.text) {
var readurl = "/userdataSet?$filter=(id eq '')";
myModel.read(readurl, {
success : function(oData, oResponse) {
debugger;
var userdata = new sap.ui.model.json.JSONModel({
"Result" : oData.results
});
var tab = that.getView().byId("userdatatable");
tab.setModel(userdata);
var i = 0;
tab.bindAggregation("items", {
path : "/Result",
template : new sap.m.ColumnListItem({
cells : [ new sap.ui.commons.TextView({
text : "{id}",
design : "H5",
semanticColor : "Default"
}), new sap.ui.commons.TextView({
text : "{name}",
design : "H5",
semanticColor : "Positive"
}), new sap.ui.commons.TextView({
text : "{email}",
design : "H5",
semanticColor : "Positive"
}), new sap.ui.commons.TextView({
text : "{mobile}",
design : "H5",
semanticColor : "Positive"
}), ]
})
});
},
error : function(err) {
debugger;
}
});
} 
// UPDATE******************
if ('Update' == oEvent.oSource.mProperties.text) {
var obj = {};
obj.id = that.getView().byId("uniqueid").getValue();
obj.email = that.getView().byId("emailid").getValue();
var updateurl = "/userdataSet(id='"
+ that.getView().byId("uniqueid").getValue() + "')";
 
myModel.update(updateurl, obj, {
success : function(oData, oResponse) {
debugger;
alert('Record Updated Successfully...');
},
error : function(err, oResponse) {
debugger;
alert('Error while updating record - '
.concat(err.response.statusText));
}
});
} 
// DELETE******************
if ('Delete' == oEvent.oSource.mProperties.text) {
var delurl = "/userdataSet(id='"
+ that.getView().byId("uniqueid").getValue() + "')";
myModel.remove(delurl, {
success : function(oData, oResponse) {
debugger;
alert('Record Removed Successfully...');
},
error : function(err, oResponse) {
debugger;
alert('Error while removing record - '
.concat(err.response.statusText));
}
});
}
}

4. Save, Deploy and Run the application. You should be able to run the application using below URL http://hostname:8000/sap/bc/ui5_ui5/sap/zcrud_demo/index.html.

6. Output:
