Configurations/Development changes in SAP PO for Proxy Scenarios

[priyanka_ajn1992_90]

Hi SAP PO Experts,

I'm relatively new to SAP PO and have been facing some challenges off late in my current PO project. Request you to provide your valuable suggestions/inputs which will help me sail through these.

Scenario Description:

I'm working on a SAP PO -> CPI migration project also ECC -> S4H migration is also happening.

There was a discussion with SAP Basis team today and they suggested on the migration approach of ECC . They are migrating in the below approach. ECC conversion to ECC on HANA and then finally to S4 HANA.

ECC -> ECC on HANA[RISE Environment] -> S4 HANA.

ECC is currently integrated with other systems Via PO [Majority using Proxy and REST Adapters].

Now , the requirement is , when the ECC gets converted to ECC on HANA (which will have different host and port), I need to connect this new system with PO using Proxy and REST connections.

Doubts I have in mind:

1. For connecting the new ECC on HANA system to existing PO interfaces using proxy , what all setup needs to be done. Should all the new configurations be done as a fresh development? (SLD creation, TS,BS, Destinations, ESR,ID etc) or is there a way to reuse the existing SLD/ID/ESR setup in PO ? Please advice for both inbound and outbound.

2. I have few REST adapters as well , So I can still have the same configurations in PO and call the same endpoint URL and call from the New ECC on HANA system without any changes in PO . Is this correct?

3. What settings should I do if I need to connect both ECC and ECC on HANA parallelly to my PO system?

Kindly help in clarifying the same.

Thanks,

Priyanka

Hi Priyanka,

1. For connecting the new ECC on HANA system to existing PO interfaces using proxy , what all setup needs to be done. Should all the new configurations be done as a fresh development? (SLD creation, TS,BS, Destinations, ESR,ID etc) or is there a way to reuse the existing SLD/ID/ESR setup in PO ? Please advice for both inbound and outbound.

--> As you mention in 3rd point to connect both systems in parallel, so you need to create new SLD objects and business systems, and use the new business system to copy the existing configuration (ID). The ESR can be reused and do not require to copy. you also need to create a new connection/destination for a new host.

2. I have few REST adapters as well , So I can still have the same configurations in PO and call the same endpoint URL and call from the New ECC on HANA system without any changes in PO . Is this correct?

--> If the host is changed then you just need to point the comm channel to new host.

3. What settings should I do if I need to connect both ECC and ECC on HANA parallelly to my PO system?

--> you can create new Business system and copy the exisitng ID configuration for parallel connection.

Harish

Hi Harish,

Thanks a lot for your answer.
1. What if i do not want both connections in parallel? Means i only need to connect the new ecc (not old one) .In this case, can I re use the SLD components? And in this case I need not have to copy the ID objects as well right? I can just re configure my channel address for receiver proxy channel and for sender proxy in the ecc , I need to create new destinations, sicf, sldapicheck etc . Is that understanding correct?

Thanks,

Priyanka
