Payment terms for Kit Component not updating

Hello,

We have an issue in changing the payment terms for the Kit components.

Create a new SB Blanket Order.

Give the Kit Parent Item.

Try to change the payment terms on ther Parent Item.

Issue:

Payment terms update on the parent Item but it did not update on the Child Items. And even On the detail revision screen the Payment terms field is grayed out for child items. unable to change the payment terms for child. did not reflect with parent item.

Please help.

Thanks,
Srinivas.
