XMLA Read/write with PPU trial

Hello,

I have a PPU trial, I am administrator. I can enable XMLA but I only see ONLY READ and ONLY WRITE. I can see READ AND WRITE.

I can acces the info through my ERP (Filemaker), but I cannot edit the values neither READ ONLY nor WRITE ONLY. I am not sure if the only problem is because I cannot choose READ AND WRITE

Thanks!
