Will ECC interface (Idoc) supported in S/4Hana 1709?

[former_member377241]

Hello SAP experts, I am looking for expertise information on SAP HANA. Let me phrase the requirement and scenarios.

Suppose we have two different ECC system as SD and MM and we have one system which is business suite on Hana for FI.
All two SAP ECC instance are interfaced to business suit on Hana FI by ALE IDOC vice versa.

Now if we migrate/upgrade all ECC instance to S/4 Hana 1709 single instance and then interfaced it with business suit on Hana for FI.
Will all the existing interface work's? As we know currently S/4 Hana is not supporting IDOC fully and has limitations.

What will would be the best approach to overcome this issue?

Can we identify before hand which interface process is supported and one which is not supported.
What are all the database table will be effected?

Appreciate your valuable response.

HI Ranjeet,

There are 3 ways to solve your issue:

1. Look into the Simplification List and search for all the iDocs you are currently using
   https://help.sap.com/doc/4698ca4ad85a4a24994b2016f366cc77/1709%20000/en-US/SIMPL_OP1709.pdf
2. Setup a Sandbox 1709 and test the iDocs directly.
   This can be done quickly and for a small amount with hosted environments
3. As an alternative, consider activating Central Finance on your future S/4HANA instance.

By the way, since you're only about 1 month out, I would recommend you to install 1809 instead of 1709. The beta version is already available.

I hope this helps.
