Receivable Transactions are being generated with due dates falling on a Saturday or Sunday (Non Business days).

How to avoid Receivable Transactions Due date falling in non business days and have the nearest Business day due date?

There is currently no functionality for this in Receivables
There are two Workarounds for the same

One Way:
Profile option, AR: Update Due Date is set to "YES" on Site Level

Navigate to Actions>Installments

Here I can change the Due Date

Requery the Invoice to see the impact

Second Way:

You can make Payment Terms like 29 Net day. For due dates falling on Saturday. Making it the nearest Business day i.e. Friday.

Similarly, you can make Payment Term 31 Net Day. For due dates falling on Sunday. Making it the nearest Business day i.e. Monday
