Program id in RFC sender

[Former Member]

Hi Experts,

Please confirm if the same program id can be used in different RFC sender channels?

Thanks and Regards

Hi,

"To identify a XI RfcAdapter sender channel within the SAP Gateway it is important that its Program ID is unique within this Gateway.So try to avoid using common phrases as Program ID like 'rfcadapter' or 'rfcToXmb'.

Hi Suma,

U can use program ID in different RFC sender channels,

but when u trig more than one RFC the network traffic between R3 to XI would be more.So better to use seperate Program ID for each RFC communication channel .

Hi Suma ,

You can use Single RFC Destination(i.e.,Program ID) in multiple Sender RFC Communication channels.

check the below link .

You need a separate TCP IP Connection for every interface with a Unique program ID.

Thanks Baskar...Please let me know the reason why we cant use the same Program ID for different Interfaces.

Hello Everyone,

I cant use the existing RFC Sender channel as the RFC metadata repository in sender channel is pointing to XI server details instead of R/3.

When I tried to use same channel am getting below error.

"Error in processing caused by: com.sap.mw.jco.JCO$Exception: (123) JCO_ERROR_FUNCTION_NOT_FOUND: JCO.Server could not find server function <<RFC Name>>

I guess the RFC metadata repository should point to system where RFC resides..Please confirm.

Thanks and Regards

Per Bhavesh reply, Program ID is tied to a RFC channel. if you could use the same channel for multiple interfaces then you can use the same program ID for multiple interfaces. IF you dont have feasibiity to use same channel for multiple interfaces then you have to create program id for each channel and respectively for the interfaces.

I agree with Baskar.

If you don't want to use same channel for multiple interfaces then you need to create one program id for each channel.

Thanks for your reply..

But I would like to know

1. What could be the impact if I use the same program id in 2 rfc sender channel for 2 different scenarios

2. "Error in processing caused by: com.sap.mw.jco.JCO$Exception: (123) JCO_ERROR_FUNCTION_NOT_FOUND: JCO.Server could not find server function <<RFC Name>>. RFC metadata repository parameters are pointing to XI server and RFC resides in R/3. Is it because of this am getting above error. Please confirm

For JCO_ERROR_FUNCTION_NOT_FOUND exception, check this help:

http://help.sap.com/saphelp_nw70/helpdata/en/f6/daea401675752ae10000000a155106/frameset.htm

A function interface or one of the data structures could not completely be retrieved from the repository

Program ID of the registered server program. The selected program ID must uniquely describe the RFC sender channel in the configured gateway (Application Server (Gateway) and Application Server Service (Gateway) parameters).

Quoting from sAP help docs

So, the impact of using the same program id wll lead to havoc

Yes, is possible.

The same program ID can be re-used for every RFC call that you want to do between SAP and XI / PI.

You can re-use the RFC destination for every RFC you want to invoke on SAP XI, there's no need to create unique program IDs per RFC.
