Hello Martjin,
We developed a custom program in python and that did the trick for us. The digest values generated by SAP and SOAP UI XML calls were different and we had to remove lot of spaces and carriage returns from the message. We have also noticed that DSA algorithms were giving issues when compared to RSA based algorithms.
I just wanted to give you this update and thank you for your support on this.
Regards,
Pranith.
