/IWFND/MED180 - Database lock for Service ... could not be set
Hello,
We are on HANA Revision 74.03 and Kernel 7.41 PL36. I created odata service and redefined GET_ENTITY method used by SAP UI 5 application.
The application is calling my odata service asynchronously multiple time (20-30) every minute to refresh page content. It is working fine,
but the NW Gateway Error log is growing. The error I am getting: /IWFND/MED180 - "Database lock for Service 'MY_SERVICE' could not be set." I am
getting 2-3 error log entries per refresh. It is not consistent. I am not able to reproduce the issue when testing the failed service call. Please, help.
Best Regards,
Zachary

Eclipse: unable to create a Gateway Connection
Installed SW (Frontend)
- Eclipse Juno
- Newest SAP Development Tools from https://tools.hana.ondemand.com/juno (ADT 2.7.5 etc)
Backend
- AS ABAP 7.40
Hello Collegues,
I've created a NW Gateway Service on the backend (Service is working correctly) and now I want to create a UI5 Application on the Eclipse site.
Before creating the project I have to create a Gateway connection first. But I'm getting a "Network Connection Error".
Connection data (host, port) is correct, also tried with IP instead of hostname already.
I'm getting the same error if I'm using the (new) ES Workspace data (sapes1.sapdevcenter.com, Port 80?).
Tried also on another PC, same error.
Any ideas?

Getting data from SAP backend into Gateway Hub
Dear all,
I am new to Netweaver Gateway. In my landscape the IWBEP component has been installed in the Gateway Hub system. In my custom OData service i want to get the data from my backend SAP ERP system using a BAPI.
I have created my custom OData service with the relevant components and have implemented the service using the BAPI method. While implementing the service i referred to the BAPI method from the SAP ERP backend system using the RFC destination (ABAP connection i.e. connection type 3) to the SAP ERP system created in my Gateway hub.
Now when i test the service, the service document and metadata XML are generated correctly. However when i test the entity set, i find that the data is NOT being extracted from the SAP ERP backend system.
What configuration/settings need to be maintained in the custom OData service so that the service refers to the correct SAP backend system? How does the gateway service determine from which system it should extract the data?
regards
Nitesh

Connectivity error to SAP gateway from Eclipse
Hi All,
I am facing an issue in connecting to the SAP Gateway from Eclipse while trying to create a UI5 app to consume the Gateway service.
Please note that the gateway is accessible via web browser.
Also, that i already checked other threads on SCN to cater to the problem & hence i have already added the required SSL certificate to the Eclipse JRE installation. But unfortunately, i am still facing the issue. Please help me at the earliest. TIA.

1. We have configured the Fiori Launchpad Client
2. We are testing the Launchpad URL with in LAN, it just works fine across all locations when we test this using Chrome Browser

Please help me understand what could be the issue?
Additional Details:

Unable to post multiple records with create deep insert
Hi,
I have implemented create deep insert functionality. It works fine for single header record and multiple item records.
When I pass multiple records (multiple header records and their corresponding item records) in payload, I am not able to fetch any records via
io_data_provider->read_entry_data( IMPORTING es_data = lt_del_mts ).
here lt_del_mts is a table of deep structure.
If I pass ls_del_mts which is a deep structure
io_data_provider->read_entry_data( IMPORTING es_data = ls_del_mts ), I am able to fetch single header and multiple item records.
PLease help.
Thanks and Regards,

How does gateway know to call CREATE_DEEP_ENTITY method?
Hi Experts,
I have implemented CREATE_DEEP_ENTITY method of DPC extension class. Also I am using POST.
At runtime how does the gateway know that it has to call CREATE_DEEP_ENTITY?
In which class the logic is written like
If HTTP method is POST then call CREATE_DEEP_ENTITY?
What is the purpose of MPC and DPC class? What is the program flow that is, which class is called first and then next etc?
Please help.
Thanks

SAP UI5 on ABAP without Gateway?
Hi All,
Within all the discussions about Gateway and OData sevices, I couldn't answer to a basic question I have... Hope someone here could answer it for me.
We have a NW 701 ABAP system with the IW_BEP Addon installed. I understand that this is enough to create OData channels from ABAP.
However, every blogs/articles goes ahead to GW_CORE as further steps to expose the OData channel as gateway services to the world. That's fine, but I'd like to know if I want to develop a UI5 application that's hosted right within the same ABAP server (using SAPUI5 runtime), then is there a way to consume these OData channels directly without the GW_CORE?
Can anyone refer me to any articles, wiki or blogs etc. that has such an information?
