Hi SPISLGAL,

Indeed if a customer is set to be 'Balance Forward' rather than 'Open Item', this means that there is no desire to apply payments to specific invoices. The desire is to let the program apply the payment to the oldest invoices for you. So it is as you say, that if a customer is defined as Balance Forward, then you won't be able to pick specific invoices to pay, either in AR or in BankRec.

If you don't have any batches in AR and are able to change the customer type from Balance Forward to Open Item, the outstanding receipt batch in BankRec will not beome corrupt. The receipt detail will remain as a 'UP' unapplied detail, but you now can see the individual invoices to apply to (ie delete the UP detail and re-select the invoices you want to pay).

But I would strongly recommend making a full backup of your data prior to making any changes like this, just in case the results of doing this are not too your liking.
