AWA 12.3.1 - SAP CallAPI: connection impossible with SAP

[Samuel BRENOT]

Hello,

We are trying to interconnect SAP with AWA through the SAP CallAPI, but the connection is rejected.

The CallAPI process ends quickly with this log:
20200910 / 114248.265 - U03004012 Could not register to the SAP gateway.
20200910 / 114248.265 - U03004008 RFC-Server version '12 .3.1 + build.1570454025760 'for SAP R / 3 ended abnormally.

We have a trace file with this message (dev_jco_rfc.trc):
Error:> Thu Sep 10 11: 42: 21,619 <RfcException raised by system [<unknown>]:
message: Connect to SAP gateway failed

And at the level of SAP, the SAP administrator gives me this log:
GwIParseAclEntry: ACCESS = local, internal, 10.252.xxx.xxx (3 entries, 3 ok, 0 error)

On the ucxsapc.ini file side:

SAP works hassle-free with TradeXpress.
To connect, TradeXpress uses the same information (gwserver, hostname), but uses a user / pwd.
However, it does not seem possible to add this in the ucxsapc.ini.

To be precise, when you work in the other direction: AWA -> SAP via a SAP connector, there is no problem and AWA can control SAP Jobs without problems.

Do you have any clues that can help us understand what may be a concern for the connection to work?

Thanks for your help

Hi Samuel,

Regarding this error : ERROR service 'sapgwxxx' unknown
Does the sapgwxxx service exist in the /etc/services file?

If not, try to create it by adding the following line at the end of the file : 
sapgwxxx           3600

Regards,
Yohan

Hi Yohan,

Thank you for your reply.
The /etc/services file was not set with the information from the sapgw service.
After updating this file, we re-tested and we are still in error but with a different message:

Error:> Tue Sep 15 08: 45: 58,386 <RfcException raised by system [<unknown>]:

On the other hand, the SAP administrator cannot find any log or trace on his server to explain the refused connection.

We will try to redo some tests soon and recheck the SAP logs.
