I receive sequences questions when start SAP PO project. In this topic, i will show you check list what should be prepared on SAP PO, SAP ECC, SAP S4 or SAP CAR.
If you are lucky, you are joining on going projects so you can inherit configuration and some connection configs stuff. If not you need to know what should be done before start SAP PO mapping.
To be honest, why do we need check list ?
When you are working in SAP Projects, there are so many things and many team are working together. We need to make sure that all dependence tasks should raise to right team / peoples to help you do.
1. SAP ERP / CAR / BW: RFC Connection
In almost integration scenarios, you need RFC accounts.
RFC Account used for SAP PO sending data via RFC. Example inbound data via IDOC
2. SAP PO: Define Business System
Depend on your integration Landscape you need to define business system in your SAP PO. Here you can define business system for SAP ERP, SAP CAR, SAP BW etc…
If business system is one of SAP System. You need to know technical system which provided by basis team or synced from SOLMAN.
Access to your SAP PO
Example, define business system for SAP S4 HANA
Business System for third party system. With third party business system, i don’t have real technical system so i can define dummy technical for them.
3. SAP ERP: Define proxy connection
Proxy necessary when we do send data with none-standard SAP interfaces like ABAP custom program.
3.1 RFC Destination from SAP S4 | CAR | BW to SAP PO
Access to SAP HANA, BW, CAR and create RFC destination for SAP PO.
3.1 Create SLD Access Data for Proxy
When you are using ABAP proxies, SAP S4 | BW | CAR need to connect to your SAPP PO system to get metadata, structures which you designed on Enterprise Service Builder. You need to show SAP know where to load those metadata by config PO information on SLD.
3.2 Integration Engine Administrator
Go to SAP ERP | BW | CAR
4. SAP ERP: Define Port
Define port for IDOC processing
4.1 Create RFC Destination for IDOC
And don’t forget to check unicode support during transfer data
4.2 Define IDOC Port
5. SAP PO: Create Production
6. Check SAP ERP Proxy URL
In some integration scenario, you need to use SOAP Adapter on SAP PO. You need to SAP ERP XI Engine, the URL below will allow you access SAP ERP with technical account.
http://[SAP ERP HOST NAME]:8000/sap/xi/engine?type=entry
When you try to access SAP ERP URL and response with SOAP message below meaning XI engine working well on SAP ERP.
Thank you for your attention and let me know if any idea.
