In AX 2012 R3 CU12, i had customized successfully the MPOS customer creation form adding an extension table for CUSTTABLE with six columns using Extensions Properties. I found a document about Dynamics 365 that explains the way to do this.
There was a little problem with Retail transaction service data: the xml file is transferred in a wrong format.
So, I applied the latest update package post CU12, with a set of update to build 6.3.5000.1468, also for binaries, hoping the problem was solved.
Instead off, Real time transaction service calls are totally changed ( seen with dotPeek... ) and Extensions Properties totally excluded from xml file sent to Head Quarter ! ! !
How it is possible, without any documentation or any warning about that ? It's crazy.
Now I would like to now if this modification is for future implementations or if the Extensions properties feature will be definitely abandoned.
Thanks.
