Restrict LE at the Invoice Header Level

Content

Hi,

Is there a way to restrict LE at the Invoice Header level?

We have 1 Ledger with multiple BUs, there by multiple LEs at the ledger level.  If user is assigned BU1 then that user should see only LE assigned to BU1 at the invoice header level but it shows up all the LEs assigned under that Ledger.

We enabled value set segment security  but that restriction is working only at distributions level but not at the invoice header level.

Can we restrict this LE at the invoice header level to access only BU1 LE by any means or any suggestions.
