How to make Credit Limit Handling work with a condition that children companies will share in parent customer's assigned credit limit.

List > Relationships > Customers > Edit Parent Customer > Credit Limit Handling will be based on parent customer's assigned credit limit.

1.    Assign hold procedure and credit limit to the parent customer.

2.    Do not assign credit limit to the children.

Navigate to the following Setups:

1.    Setup > Company > Enable Features > Accounting tab > Consolidated Payments = True.

2.    Setup > Accounting > Accounting Preferences > General tab > Accounts receivable section > Customer Credit Limit Handling then, select how you want to handle credit limit.

3.    Setup > Accounting > Accounting Preferences > Apply Payments Through Top-Level Customers Only = True.

This means every time you create a transaction and the customer exceeded the credit limit assigned to the parent then a warning message will prompt telling you that the customer has already reached the maximum credit limit assigned.
