SLA rules for CASH accounting class

Summary:

Dear All,

we have created a rule so that the ‘intercompany’ segment is inherited from the customer master data.Specifically, from the ‘Manage account rules’ task, we created a rule as shown in the screen.

After, through the task "Manage Accounting Method" we have included this rule in the cash event class, as shown below.

Despite this, when we post a receipt, the system continues to inherit the entire accounting combination from the bank account without modifying the intercompany segment, taking into account the rule.

Do you know anything more about this? Is it possible to find a solution? Could there be another account class that I am not considering?
