Register OData Service

In this blog, I will try to cover how to register OData service, once we have created an OData service in SEGW. After registering only we can access the SAP OData service. By registering, we mean we open our service to the internet. We can Register the service in two ways:

• From the transaction SEGW
• From the transaction /n/IWFND/MAINT_SERVICE

Steps to Register an OData service using SEGW

Once the OData is generated, now it is the time to register the service. Once the service is registered, then only it can be used anywhere.

To generate an OData, follow the given steps:

Double click the node Service Maintenance

Select any System and click Register as shown below:

Enter an Alias, if asked as shown below:

Now, in the next screen you get following options:

Field	Description
Technical Service Name	This is auto generated service name
Service Version	It is auto generated service version
Description	It is the Description of the OData you have mention earlier
External Service Name	It is same to the auto generated service name
Namespace	It is by default bank
External Mapping ID	It is by default Empty
External Data Source Type	It is by Default set to source type C
Technical Model Name	It is auto generated Model Name
Model Version	It is auto generated Model Version
Package Assignment	Assign your package name here, or just choose Local Object from the button below. It will be then $TMP
ICF Node	It is by default “Standard Mode”
oAuth Enablement	It provides option to add extra authentication, in case you need oAuth2 enablement choose it, else leave it blank

 

In our case, we just need to choose package and click confirm, as shown below:

Once the service is registered, the Registration will turn green, as shown below:

Test the OData service

To test the OData service, click the SAP Gateway Client button, as shown below:

It will open a new screen, here click Add URI Option as shown below:

Open the Service Maintenance Screen using the transaction /IWFND/MAINT_SERVICE. The given screen will open:

Click “Add Service” button. It will open “Add Selective Services” popup.

Filter your service by entering it in the field “External Service Name” as shown below and click the search icon.

Now, the above search will return your OData Service name. Select your service and click Add Selected Service

Now, assign your package name to the Service as shown below. In case, you don’t have package name, either click on “Local Object” or write $TMP in the package assignment. Then, save the above settings.

Now, a pop up will open saying “Service <your service name> was created and its metadata was loaded successfully

Now, go back to the transaction /iwfnd/maint_service and filter your service again. This time select your service and select SAP Gateway client

The Filter will open this popup, enter your details here and click execute (the green button).
