Remove soapenv:mustUnderstand="1" from the Soapenv Header

Hi

We need to interact with a 3rd party that it doens't allow the use of the soapen:mustUnderstand="1" header param in a WS Security implementation enviroment. We are facing this issue using SAP PI 7.11 and a soap 1.1 adapter.

We have found some post suggesting the use of transformations but we are searching for an easier/cleaner way to achive this premise.

Any ideas?

Thanks in advance for your help!!!
