BC Error: Attempt to de-reference null object when clicking Apply to Contract button
An "Attempt to de-reference null object" error can occur when applying a change request to a billing contract. This error is caused by new contract lines that were cloned and incorrectly reference an active contract line item. To resolve this, the cloned lines must be deleted and manually recreated without the reference to the active line. This ensures the change request can be applied to the original contract.
