When you try to assign a Company to an Account, system throws below error message:
Customer or supplier is invalid
Company XYZ (Company Name) not allowed, as it corresponds to the account ABC (Account Name)
Reproducing the Issue
- Go to Account Management work center.
- Select Accounts view.
- Locate an Account.
- Select Edit button and choose Financial Data option.
- In the Companies section, select Add Row button.
- Select Company XYZ.
The cause for the issue is that you are trying to assign the Company XYZ to a Account which was actually created out of the Company XYZ.
This is not allowed because then you could make revenue with yourself, which would be quite a bit strange from a business perspective (and probably legally prohibited).
The system works as designed.
