Bank account already exists issue

[SAPSupport]

Customer requires to create bank account and assign it to multiple chart of accounts but system prompts error "bank account already exists".

I tried to assign multiple CoA eg. g/l A and g/l B to same bank account entry but system prompts error "G/L account type not supported in multiple house bank account linkages" (FCLM_BAM_MAINT859)

Please advise cause and solution or workarounds so customer can create bank accounts?

--Cause--

When the bank account must have multiple house bank accounts, then the bank reconciliation account cannot be assigned to these house bank accounts.

Use normal Balance Sheet G/L Accounts
