Update account no in the house bank account

Hello

I am trying to update the account no. in the house bank accounts but I am getting the next error u2018field cannot be updated (ODBC-1029)u2019. I have checked that the account its not in the company details, neither in the business partners or in the payment methods. I have made some tests, and I have add a new account and assign it in the master data in BP, after I have assign a different one, and then I am unable to edit the account in the house bank account.

How i can update the account no. in the house bank accounts?

Thanks

Jacobo
