As you remember in order to create test cases you had to create configuration object manually per tested interface, where you would define all rules and parameters. Not anymore! As of Service Pack 11 release 006 you will be equipped with SAP PO Wizzard which would handle this task automatically.Read More
SAP Process Integration is the most common SAP middleware platform so far. Its widely used to connect various SAP and non-SAP systems, providing a single point of integration. According to SAP PI dual stack installations (ABAP and JAVA) will be supported by SAP only until the end of 2020. Very likely in the next couple of years there will be an increase in the number of SAP PI migration projects as SAP XI/PI dual stack installations will need to be migrated to a single stack JAVA only SAP PO architecture.Read More
Since SP11 integration with change management software is available. Int4 IFTT will create automatically incidents regarding particular test case, update their status, close existing and creating new ones. You will be also enabled to manage incidents directly from test cockpit manually.
With this feature Continuous Testing implementation is easier and there is not chance to overlook the defect. Check this blog to learn more!
Nowadays, more and more people focus on the user experience in the IT world. When we visit websites or work with applications, we expect that the usability of the tool will allow us to work or find necessary information in the shortest and the most efficient way. In the SAP you can also increase the user experience by implementing the predictive (type-ahead) search helps.Read More
Have a look at the picture above. What if, this huge jam was a result of a failing interface to or from the warehouse. Whether the root cause of the error is in communication, mapping, or anything else, you could quickly find out using the interface monitors, like the ones provided by SAP PI or SAP AIF. But on the other hand, from those monitors you would not see the implication that these errors have on the company’s business processes. Yes, in this case probably looking out the window would be enough? But, it is not always that obvious.
Recently, during my last AIF project, we encountered a challenge and we wondered if it is possible to save the payload of the response message for the outbound synchronous proxy interface in SAP AIF. We found a solution, but since that time many of our colleagues working with SAP AIF encountered the same challenge and that was the reason why we decided to write this blog with our proposed solution. This blog is written in cooperation with my colleague, Krzysztof Łuka.
Imagine the situation when you have to configure the outbound synchronous proxy interface in SAP AIF and you have to save the content of the request and the response messages. If it comes to the content of the request message – there is no problem. You may encounter a challenge if you want to save also the response of the synchronous message.
In this blog we will focus only on the SAP AIF part – we won’t describe how to create objects on SAP PO side. We will use the ABAP report to send the request message with the message ID from ERP system to SAP PO. We expect to receive back in the synchronous response the SAP PO message key that is related to the message ID we sent in the request.
This is how sample synchronous request message looks like (with the message ID):
And below you can see the synchronous response message with message key from the above request:
First, you have to generate and activate Service Consumer that will be used in order to send the request from ERP to SAP PO.
Then you have to copy the name of the class for the generated Service Consumer. In our case, it is /INT4/CO_SI_O_GET_MESSAGE_LIST.
This class is necessary in order to create SAP AIF interface.
In next step go to AIF Customization ( /AIF/CUST transaction ) and go to Interface Development -> Define Interfaces. We will have to create new entries: one interface for the request message and the second interface for the response message.
First, create a new entry for the request message. Type OPRGMSG001 as the interface name and 1 as the interface version.
Then Provide your Service Consumer class (in our case it’s /INT4/CO_SI_O_GET_MESSAGE_LIST ) in the class Proxy Class Outbound field and choose the proper method that will trigger sending a message to PO.
Once you provide proxy class outbound – automatically RAW Data Structure and Record Type in Raw Structure should be filled. Please provide the same structure in SAP Data Structure as was filled into RAW Data Structure and mark Move Corresponding Structures checkbox, as it is visible on the screen below:
As a next step, we have to create another entry in Define Interface node. This time we have to do it for the Response Message.
Add a new entry with Interface Name: IPRGMSG001, interface version: 1. In Proxy Class Inbound provide the class of your Service Consumer. In our case, it is /INT4/CO_SI_O_GET_MESSAGE_LIST. Then click enter and again your Raw Data Structure should be filled automatically. Right now we are interested in the response message and because of this, we have to provide the type of the structure that is used as the exporting parameter of our class for the service consumer. In our case it is /INT4/MT_GET_MSG_LIST_RES as it’s visible on the screen below:
Use the same structure in SAP and RAW structure and mark Move Corresponding checkbox. Please also make sure, that you have chosen specific proxy method as shown on the screen below:
Right now we have to make sure, that proper Engine is used for both of our interfaces. Go to AIF Customization (transaction /AIF/CUST ). Then open Interface Development -> Additional Interface Properties -> Specify Interface Engines node and set for both interfaces Proxy as Application Engine, XML as Persistence Engine, AIF Index Tables as Selection Engine and AIF Application Log as Logging Engine.
The last step is to create ABAP Report, that will trigger sending the message from ERP to SAP PO.
Create a new program in transaction SE38.
In order to make this program simpler – we will hardcode the message ID that will be sent to SAP PO. We are using function module /AIF/SEND_WITH_PROXY to send the data out from ERP. We have to provide a namespace, interface name and interface version of our interface we created in AIF. In this step, you have to provide an interface used for the request message ( ‘OPRGMSG001’).
In the RESP_SAP_STRUCT changing parameter we have to provide a structure of the response, that we used in the IPRMSG001 SAP AIF interface. Then in the SAP_STRUCT changing parameter, we have to provide filled with the data structure for the request interface.
In the end, we have to use method /AIF/IF_PERSISTENCY_ENGINE~UPDATE of class /aif/cl_persist_engine_xml in order to store the response payload in SAP AIF. While using this method we have to provide details of the second interface in SAP AIF, that will store the response message.
Please see the whole code snippet for this program below:
CONSTANTS: lc_ns TYPE /aif/ns VALUE 'ZDEMO', lc_ifname TYPE /aif/ifname VALUE 'OPRGMSG001', lc_ifver TYPE /aif/ifversion VALUE '1', lc_ns_resp TYPE /aif/ns VALUE 'ZDEMO', lc_ifname_resp TYPE /aif/ifname VALUE '1PRGMSG001', lc_ifver_resp TYPE /aif/ifversion VALUE '1'.

IF ls_request-mt_get_msg_list_req-message_id IS NOT INITIAL. CALL FUNCTION '/AIF/SEND_WITH_PROXY' EXPORTING ns = lc_ns ifname = lc_ifname ifversion = lc_ifver appl_log_function = 'AIF_SEND_WITH_PROXY' do_commit = 'X' iv_persist_xml = 'X' IMPORTING ximsgguid = lv_msguid TABLES add_return_tab = lt_bapiret CHANGING resp_sap_struct = ls_sap_resp sap_struct = ls_request error_string = lv_error_msg EXCEPTIONS persistency_error = 1 status_update_failed = 2 missing_keys = 3 interface_not_found = 4 transformation_error = 5 general_error = 6 OTHERS = 7. ENDIF. "Persist response message GET REFERENCE OF ls_sap_resp INTO ls_xi_data-xi_data. ls_xi_data-msgguid = lv_msguid. ls_xi_data-ns = lc_ns_resp. ls_xi_data-ifname = lc_ifname_resp. ls_xi_data-ifver = lc_ifver_resp. CREATE OBJECT lo_xml_pers. IF lo_xml_pers IS NOT INITIAL. GET REFERENCE OF ls_xi_data INTO lo_data. TRY. CALL METHOD lo_xml_pers->/aif/if_persistency_engine~update CHANGING cr_xmlparse = lo_data. CATCH /aif/cx_error_handling_general . ENDTRY. ENDIF.
Right now we can run the report. If the proxy call was successful we should see a new entry in transaction /AIF/ERR with the payload in the outbound interface OPRGMSG001 with the request message and new entry in with the payload of the response message in interface IPRGMSG001.
Below you can see the request message with the content. Message text automatically contains the information in which interface the response was processed:
In order to make sure that the response is visible we’ll go to the second interface for the response message. As you can see on the screenshot below – response message with the payload is there:
How do you like this approach to save the message payload? Please let us know in the comments!
PS. I have a big pleasure to invite you on SAP Teched at Barcelona that will take place in October. As the INT4 team we will be one of the exhibitors and we will be presenting our SAP certified automated regression testing and service interface virtualization software – IFTT.
If you want to learn more about this tool or if you want to ask me or Michal Krawczyk SAP AIF or SAP PO related question we will be available for you at our booth everyday from 13:00-14:00 everyday! See you there!
I can bet, that if you use SAP AIF you are familiar with AIF Monitoring and Error Handling (transaction /AIF/ERR ). Here, we can monitor and perform actions for specific interface. In addition to this transaction SAP AIF also gives us opportunity to monitor all interfaces in one place. In this blog we are going to set up interface in SAP AIF Interface Monitor (AIF/IFMON transaction). Let’s imagine the situation, that you are responsible for monitoring several interfaces. Monitoring interfaces in /AIF/ERR transaction is very helpful, although it still can be time consuming if you just want to have a quick overview what is going on in all interfaces you are responsible for.
Hi there! In this blog I will show you can you can use SAP AIF multi index table and single index tables in your interfaces.
This blog is the extension of the previous blog: How To Create a Single Index Table in SAP AIF and therefore some steps will be explained in a more general way. You can always visit the previous blog in case you occur any issues with details, but I believe that you won’t have any problems, as you mastered this knowledge last time reading the previous blog! 🙂
Have you ever heard about single index table in SAP AIF? Have you ever encountered the issue while you were looking for a specific message in Monitoring and Error Handling? Let’s imagine the situation, that you receive tons of inbound messages every single day and you want to find a message with a specific purchase order number in your AIF Interface, but you don’t know what is the AIF message ID that contains this specific Purchase Order number.
Here, single index table in SAP AIF with custom selection screen for the interface come to help us!
