SAP Fiori Inbox extension is a common extension scenario in most of the S/4 HANA Projects .This blog focusses on selection of data during the first level of approval in workflow and passing it over to the other level of workflows.
These are below steps to be to achieve this:
- SAP Odata Extensions
- Extension of the Workflow container to fill in the extended fields using the BADI /IWWRK/ES_WF_WF_WI_BEFORE_UPD_IB
- SAP UI5 Extenstions using adaption of Views and Controllers
- Use the Extended Ui5 Application and configure the Fiori Launch Pad Designer with the new application ID and remove the original UI5 application from the Role
The below diagram refers to the possible places where the UI extensions are possible in Fiori INBOX
We will refer a simple scenario where in first level approver will be able to select the second level approver from a list of users and provide some comments for the second level approver.
Step 1 ODATA Extension:
- Extend the standard Odata Service /IWPGW/TASKPROCESSING with Z_TASKPROCESSINGDEMO
- Now navigate to the entity Task and extend with the additional field User ID, User Name, Comment and Visibility fields for User ID and Comment and other Approval Data if required.
- Create new entity to fetch the list of Users and their names to be displayed for the first level of approval
After the service generation implement the code in the DPC_EXT class as shown below
Redefine the method ENTITYSET_TASK and write the below code .
The below code will read the workflow container and display the required values and also sets the visibility of the Approver selection and comment field selection it appears only for the first level approver for selection
method entityset_task.

ENDMETHOD.Step 3 Implement the SAP UI5 Extensions:
There are multiple ways where we can extend the Fiori Inbox front end as shown in the below links:
https://help.sap.com/viewer/d2c296c4f32d4f2a9e3752f58d5ef222/2.0%202017-05/en-US/ddfc595461fce630e10000000a44538d.html2118812 – How to Extend SAP Fiori My Inbox – SAP ONE Support Launchpad
The above SAP Note provides the cook book for the extensions .
The below section is referred from the cook box for the view and controller extensions .
The following picture gives an overview about which extension points to use when you want to extend a specific section of the application screen:
The following picture gives an overview about which extension points to use when you want to extend a specific section of the application screen:
S2.view.xml
- CustomerExtensionForObjectListItem
S3.view.xml
- CustomerExtensionForObjectHeader
- CustomerExtensionForInfoTabContent
- CustomerExtensionForNoteTabContent
- CustomerExtensionForAttachmentTabContent
- CustomerExtensionForAdditionalTabs
- CustomerExtensionForAdditionalDetails
Controller Hooks:
The below extensions are performed for the inbox extensions:
Create a extension project for the standard Fiori application CA_FIORI_INBOX
Add the below code in the Manifest.json
"title": "{{SHELL_TITLE}}",
"dataSources": {
"TASKPROCESSING": {
"uri": "/sap/opu/odata/sap/ZTASKPROCESSINGDEMO_SRV;mo",
"settings": {
"localUri": "./localService/metadata.xml"
}
},
"APPROVER": {
"uri": "/sap/opu/odata/sap/ZTASKPROCESSINGDEMO_SRV;mo",
"settings": {
"localUri": "./localService/metadata.xml"
}
}
},We will be extending S3 View and controller in order to show the selection of the users:
Implement the S3 View for information tab extension S3_CustomerExtensionForInfoTabContentCustom.fragment.xml’
<core:FragmentDefinition xmlns:core="sap.ui.core" xmlns="sap.m" xmlns:form="sap.ui.layout.form" xmlns:layout="sap.ui.layout"
xmlns:sap.ca.ui="sap.ca.ui" xmlns:suite="sap.suite.ui.commons">
<layout:VerticalLayout class="sapUiContentPadding" width="100%">
<form:SimpleForm id="customAttributesContainer1" editable="false" layout="ColumnLayout" title="{i18n>Inboxext}">
<form:content>
<Label visible="{detail>/CommentVisibility}" text="{i18n>Comments}"/>
<Text visible="{detail>/CommentVisibility}" text="{detail>/Comment}"/>
<Label visible="{detail>/UserVisibility}" text="{i18n>Approver2}"/>
<ComboBox visible="{detail>/UserVisibility}" showSecondaryValues="true" id="Approver2" filterSecondaryValues="true"
items="{ path: 'oApprover>/WfApproversCollection', sorter: { path: 'UserID' } }">
<core:ListItem key="{oApprover>Userid}" text="{oApprover>User_First} {oApprover>User_Last}"/>
</ComboBox>
</form:content>
</form:SimpleForm>
</layout:VerticalLayout>
</core:FragmentDefinition>In order to data to appear on the S3 view also extend and rewrite the controller and do the below changes:
In the function onExit: function () comment the code in order to avoid any issue with cache
// this.oComponentCache.destroyCacheContent();
// delete this.oComponentCache;
// if (sap.ca.scfld.md.controller.BaseDetailController.prototype.onExit) {
// sap.ca.scfld.md.controller.BaseDetailController.prototype.onExit.call(this);
// }To send the details of the approver 2 add the below function at the end of the controller
_sendActionext: function (sFIName, oDecision, sNote, fnSuccess, fnError) {
oUrlParams.Approver2 = "'" + oDecision.Approver2 + "'";
this.oDataManager._performPost("/" + sFIName, oDecision.SAP__Origin, oUrlParams,
$.proxy(function (oDecision, fnSuccess) {
this.oDataManager.fnShowReleaseLoader(false);
// remove the processed item from the list
this.oDataManager.processListAfterAction(oDecision.SAP__Origin, oDecision.InstanceID);
this.oDataManager.triggerRefresh("SENDACTION", this.ACTION_SUCCESS);
this.oDataManager.fireActionPerformed();
// call the original success function
if (fnSuccess) {
fnSuccess();
}
}, this, oDecision, fnSuccess),
$.proxy(function (oError) {
this.oDataManager.fnShowReleaseLoader(false);
// call the original error function
if (fnError) {
fnError(oError);
}
//refresh the list after error and select a task accordingly
this.oDataManager.processListAfterAction(oDecision.SAP__Origin, oDecision.InstanceID);
this.oDataManager.fireActionPerformed();
this.oDataManager.triggerRefresh("SENDACTIONEXT", this.ACTION_FAILURE);
}, this.oDataManager), sErrorMessage);
}Additionally pass the date of the visibility Enhance the S2 Custom Controller using the extHookGetPropertiesToSelect fragment extension:
sap.ui.controller("cross.fnd.fiori.inbox.INBOX_EXT.view.S2Custom", {
extHookGetPropertiesToSelect: function () {
var select = [ "Comment", "UserVisibility","CommentVisibility"];
return select;
}
});Step 4
This step can be referred from the cook book
This way we can enhance the SAP Fiori inbox extensions with Odata and UI5 Extensions for performing custom actions during the approvals
