Hi @nhatnghetinh 

Thanks for your response. Yes, I entered the web and the account. and clik Load schema, it shows the error like the screenshot. 

Hi @HazelLiu0601 

It is possible that the Report Designer version is different from the Acumatica version and is not compatible.

Try reinstalling Report Designer with the same version as Acumatica.

Hi @HazelLiu0601 ,

I believe, you have setup more than one company in your Acumatica instance.

While logging into the report designer you need to add @CompanyName after the login username as shown below.
 

hope, it helps!

Hi everyone, redownload and add @ company name still cannot log in. 

I could log in now. Thank you for all the support.
