ECC issues while upgrading PI 7.1-> 7.4 (Dual Stack)


Hi,

We are a big Food Manufacturing Company and are beginning a project of PI upgrade very soon where we will be upgrading from PI 7.1.1 to PI 7.4 Dual Stack

We have a variety of Interfaces between SAP ECC and PI  which will be slowly migrated to PI 7.4 Dual Stack first and then later,we will decide upon   PI 7.4 Single Stack Conversion.

During the course of Upgrading we are facing the following issues :

a)  While converting  IDOC->PI and PI -> scenarios   what are the different steps to consider in ECC side , so  that the IDOCS in the current running interface can point to both SAP PI 7.1/1 Production and newly developed PI 7.4 Development box at the same time for Testing , before Cutover can happen

b) For Proxy-> PI and PI -> Proxy scenarios, what steps can be taken care in SAP ECC side , for the proxy to point to two PI integration servers at the same time , PI 7.1. Production and PI 7.4 (newly developed=)

c) Same for  RFC-> PI and PI -> RFC scenarios.- whast changes can be made?

Most importantly if we are not migrating our scenarios in ID part through Migration Toolkit, can you please suggest a document or How to -> for transporting the Integration scenarios/components in bulk or strategy for the same.

Please help  !

Regards

Vikram

    Hi Vikram,

    My few cents:

    a)  While converting  IDOC->PI and PI -> scenarios   what are the different steps to consider in ECC side , so  that the IDOCS in the current running interface can point to both SAP PI 7.1/1 Production and newly developed PI 7.4 Development box at the same time for Testing , before Cutover can happen

    >>> For 7.4 I believe you will setup IDOC_AAE and migrate the Existing Idocs to IDOC_AAE. You can refer the following guide for IDOC_AAE configs.

    http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/5050119d-9c47-3110-eab0-d90ebd211e69?QuickLink=index&…

    Inorder to route it to PI 7.1 or 7.4 you will map the corresponding Port in Partner Profile we20 to forward the IDOC either to Idoc or IDOC_AAE port. For Inbound there is no changes in PP required.

    b) For Proxy-> PI and PI -> Proxy scenarios, what steps can be taken care in SAP ECC side , for the proxy to point to two PI integration servers at the same time , PI 7.1. Production and PI 7.4 (newly developed=)

    >>> For Proxy in PI 7.4 you need to config SOAP over XI as mentioned in the following link.

    http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/70066f78-7794-2c10-2e8c-cb967cef407b?overridelayout=t…

    You need to maintain the Sender IDs in SXMB_ADM of your ECC to forward it to either conventional IE or AAE URL. Refer the blog for details (pg 5&6)

    Most importantly if we are not migrating our scenarios in ID part through Migration Toolkit, can you please suggest a document or How to -> for transporting the Integration scenarios/components in bulk or strategy for the same

    >>> If you are not using Tools, you can do a .tpz file Export of your ESR and ID objects(from 7.1) and Import those in 7.4 manually using File Transport option.

    Hope it helps

    • Hi Vikram,

      AFAIK there is no such tool for Classical to Classical migration. In this case you can use the File Import/Export option (.tpz) for both ESR and ID objects.

      You just need to ensure that you have the corresponding Business Systems / Components available in your ID prior to Import into New system ( dont recall if there were any CIM or GUID related errors, nor there were any CTS errors).

      We did a phase wise migration wherein, initially the Simpler scenarios (1:1 mapping/ File Transfer) were upgraded & tested; followed later by Complex ones.

      Hope this helps

      Azhar

    Are you trying to connect ECC production system to PI production and PI development system in parallel? Why do you want to connect a production instance and development instance?

    Azhar has already provided pointers and you can find lot of documents on SCN about IDOC_AAE/ Proxy using SOAP.

    Hi Vikram,

    For 1 and 3

    Since you are not shifting to the single stack IDoc and RFC, there shouldn't be any need of making changes in 7.4. You can directly import the dump into 7.4 and work with it.

    When you are moving to single stack configuration at that time you will require IDoc_AAE adapter instead of IDoc, configuration for which can be found online easily.

    Note: In Inbound standard Idocs the constants like begin, etc should be mapped with 1. In earlier versions they can be mapped with any constant values.

    Regards,

    Nishant
