Hi Kalyan,
The error which you are referring to corresponds to FI domain. It would be ideal to ask the FI consultant to check whether the relevant controlling area is assigned to the company code.
These are normally taken care of during the creation of company code.
However if you wish to check the same you can check the following configuration path
Enterprise Structure -> Assignment -> Controlling -> Assign company code to controlling area
And this is maintained in the ECC system.
