3 company codes all added a new bank code B. Defaults were setup in AP and AR. In one of the companies bank code B will not default, nor will it let you type or use the lookup to change from the old default of A in check and electronic payment processing. However, it will let you choose any of the other bank codes available. It defaults correctly in manual check entry. Can't find anything in the knowledge base and not quite sure how to fix it. Deleting and reentering not an option, deposits and checks associated already. v2020 Std
