Define Account Determination for Bank Clearing Accounts subaccount grayed out

[Gabor5]

Hello Experts,

In CBC activity Define Account Determination for Bank Clearing Accounts I enter the subaccount but after saving it's grayed out. 

I found this KBA Note https://me.sap.com/notes/3312572 but it's note useful. 

KBA Note: 

Configuration steps:

In Configuration Activity 101024 'Make Global Settings for Electronic Bank Statement' assign bank subaccount to an account symbol.

In Configuration Activity 103557 'Assign Account Symbol to Payment Methods' assign payment method to account symbol and country/region key.

What could be the problem?

Both settings are fine in my understandings and yet when I try to enter save the subaccounts it's still grayed out -->

Thank you in advance!
