DIXF import file size limit

Hi all,

I am trying to do an import operation wherein I am sending my xml file from postman to D365, however I am getting an exception. I am guessing it is because of the huge file size since on reducing the size its working fine for me. Could anyone henceforth please suggest the file size limitation/ number of records limitation that D365 expects so that I can advise my customers accordingly.

Thanks in advance!
