Tiered Markup (Discount List) is not populating GL_DATE

Summary:

Tiered Markup line has a blank/null GL_DATE in RA_INTERFACE_LINES_ALL.

Content (please ensure you mask any confidential information):

We are using a Discount List that contains a tiered markup.  The markup amount appears correct on the SO line, and when the order is shipped, I see two rows in ra_interface_lines_all.  The first row is for the ordered item, and the second row is for the charge.  The first row contains a gl_date of 7/27/25.  The second row's gl_date is blank. Due to this, Oracle imports these lines as two separate invoices (due to mandatory AutoInvoice Grouping rules.)   We need these to be one line so the marked-up amount appears on the same invoice as the shipped item.
