AR Intercompany invoice for internal sales order

Hi,

We facing an issue with one internal sales order. There are couple of internal sales order.

For one sales order the AR intercompany invoice was generated, but AR intercompany invoice is not generated for another sales order. In order line, i could see the invoice interface status code is showing as Not eligible for invoicing.

I am not sure what causing the issue for this sales order. Can you please let me know why the intercompany invoice is generated for one sales order, even though the order line having interface status code as not eligible for invoicing.

For 2nd order, no AR intercompany invoice has been generated system, how can we generate intercompany invoice for this order.
