Problem of receive & send data with sap sync in biztalk server 2020

edward park 1 Reputation point

We are doing the integration between SAP and BizTalk by RFC Synchronous.
We are install SAP NCO30. ( 32 & 64 bit all )

My scenario is as follows.

  1. receive data from sap using RFC.
  2. Process the received data.
  3. send response data to sap from biztalk.

If an error occurs in wcf-sap dapter in step 3( wrong response action or xmlparsing error ),
SAP has not received the data.

after this situation,
Biztalk Server re-executes the DATA received through RFC indefinitely.
No See any Transaction info in SAP SM58 screen.

We are testing same situation on Biztalk server 2016 using Connector Type value is "classic RFC".
this doesn't happen.
Is this an SAP NCO30 issue?

I tested someting the following

  • receive sap host runs 32bit & 64bit.
  • change value of WCF-SAP Receive Location
  • Binding > Metadata > ReceiveIdocFormat = Rfc
  • Messages > Error Handling > Suspend request message on failure value check

What can i do more?
I need yours help...
