AP / AR Netting Issue - URGENT

Dears,

In AP / AR netting we are facing the following issue:

- A supplier has an uploaded opening balance dated August 2013, the netting box in his address book was not flagged, so we did the following:

1- updated netting flag,

2- create a customer master for him,

3- updated the netting flag in the transaction via P0411S ( Alias NETST ) to be 1

But when we try to do the netting, this document does not appear in the Form W03B455D Sub-form W03B455I & H, while it is there in the Form W03B455B sub-form W03B455C & D
