In order to allow members to open a savings sub-account in online banking, use Tool #506 Member Rate Maintenance. Then select Share Rate Update.
On the next screen, the column OLB will control which products members can choose from. Enter a number into the column for the product to add it to the online banking rate board (the products will be listed sequentially). Once a number is entered and the forward arrow is used, the default configurations for each product can be configured by clicking the pencil icon next to the OLB column. (This pencil icon will not appear until this step is taken.)
Other considerations apply, such as setting up sales text and order that the product appears on the rate board. Refer to the documentation below for more details.
