This error occurs when posting Cash Receipts and indicates a mismatch in the DA Due Date between Fairwater and D365. The source issue tends to be a DA Sync error when the DA is billed and if it is addressed at the time of the error there is not an issue. But, if the DA is added to D365 in a subsequent Accounting Period then this becomes a problem. To resolve we adjust the DA Due Date in D365 to match the Fairwater DA Due Date.

1. Go go Accounts Receivable / Open Customer Invoices
2. Select your invoice from the list
3. Click on Transactions
4. Click on Open Details
5. Modify the Due Date to match the Fairwater DA Due Date
6. Close
7. Re-Sync the Cash Receipt Entry in Fairwater

Port offices sometimes will use the SYNC PROFORMA button in Fairwater to submit proforma to Simply5, but then later, will add more services or fees and then try to click SYNC PROFORMA button again.   Please note that this will not work. 

If you need to change a proforma already synched, then you must go to the Simply5 “Proforma Entry” screen for that call, and click on the “Recall” button at bottom of screen in order to recall the proforma (see bottom of below screenshot).  Only then can you go back to Fairwater, and click the SYNCH PROFORMA button again to submit updated proforma. 

Please note that if the Simply5 screen shows that the PDA has already been approved by the Hub or Client (2nd screen shot below), then the “Recall” function will not work, and you will not be able to submit any changes unless you write to S5 Finance Hub and ask them to RESET the PDA. After they RESET you can then update the PDA in FW and re-sync.
