Team, 

After the implementation of E-Invoicing in India, Certain fields have been made mandatory in the Customer Details and also in the Vendor Details.
Can those fields be made mandatory? Like Street. NO, the Phone number must be between 3 to 12 characters, then in the invoice module, the Project name should be between 3 and 21 characters the Customer notes also have some restrictions with a tool tip or help text.
This is URGENT in nature as finding it very difficult to train our users on this.
