Dispute Management - Read Error in FBL5N

Hi Experts

We have an issue while creating Dispute cases

When we are creating Dispute cases for multiple invoices in FBL5N, we have getting the Read Error in the place of Dispute case ID,   Please help us to come over this issue.

1. Why this is creating like that ?

2. How do i correct it to bring Dispute case ID in the place of Read Error ?

3. How do re create Dispute case for the invoices which have read error ?

Thanks allot if you advice to rectify the issue.
