This error appears when you try to open another company, which has the same name as that of the loaded company.


Load only one company at a time if the names of the companies are identical.


When a company of a particular name is loaded, TallyPrime will not allow you to load another company of the same name.


You need to load the required company, and alter the Company Name from Company Alteration screen. You can prefix or suffix the Company Name to differentiate it with the other companies having the same name.

For example, if you have two companies with the name ‘Test Co.’, you can suffix the name of one company as ‘Test Co. – South Region’. You can retain the same Mailing Name and Address for both the companies.

Now, without closing the ‘Test Co. – South Branch’ company, you can load the second company, Test Co. The data will get loaded.
