Invoice value for services is non editable

Hello All,

The scenario is, when we are trying to book / park invoice against a service entry sheet then the line item value in the invoice document is greyed out and is not editable. This is picularly happening when invoice is being booked / parked for the service entry sheet having more than one service line items.

This problem is not faced when service entry is with single line item.

Please help.

Thanks and regards.
