TRX_ATTR is not working for credit memo account rule

Summary:

Issue in creating credit memo rule with TRX_ATTR

Content (please ensure you mask any confidential information):

Hi Team,

When we try to create an account rule based on the DFF (TRX_ATTR) defined at the AR transaction header level, the rule is not working as expected.
Sample Rule:
"Credit Memo Transaction Source Name" = Distributed Order Orchestration AND "TRX_ATTR1" is not null
Then the constant value should be 812070.
When we apply similar logic for invoices, it works without any issues:
"Transaction Source Name" = Distributed Order Orchestration AND "TRX_ATTR1" is not null.
However, when we try to use the same logic for credit memos, it does not work as expected.
