Cancelling SES Line Item After Invoice and Payment

[fairulnizam1]

I am facing an issue with a Service Entry Sheet (SES) in our system and would appreciate any advice or solutions. A user has created an SES with two line items, and one of these line items has been invoiced and payment has already been made to the vendor. The user has now realized that the amount on the first line item is incorrect and needs to be canceled. However, when attempting to cancel the first line item, the system does not allow this action because the second line item has already been invoiced and payment has been made to the vendor. Is there any solution to resolve the incorrect amount on the first line item while keeping the second line item, which has already been processed for invoice and payment? Any suggestions or best practices to handle such situations would be greatly appreciated. Thank you in advance for your help!
