Question:
How can the signature/certificate for Connect to SAP be deactivated?
Solution:
You need to deactivate the signature on DocuWare and SAP side.
On DocuWare side use DocuWare Administration, go to Server > Connections.
Disable the flag 'Enable secure communication' and restart the SAP HTTP Service.
On SAP open the transaction 'OAC0'. Enable the flag 'No signature'.
