Multiple Records Deletion in Siebel Apps

Hello Oracle Support,

We have performed the multiple Agreement Line item deletion by clicking a custom button on AgreeLineItem applet which invoke the escript coding on Delete Method at BC level.

There is another operation performed before deletion with AgreeLineItem and corresponding child of agreement line item (i.e. Agreement Incentives) by calling another Custom Business service through PreDelete Method of same AgreeLineItem BC.

But the issue is that custom business service is only invoking for its child of agreement line item (i.e. Agreement Incentives). Hence we are losing the instance of Agreement line item.

Is there any best practice we need to follow in case of multiple deletion? Does Siebel application Supports the multiple deletion functionality?
