There’s an issue where a single ABHA number is being patched to multiple beneficiaries, which is causing discrepancies in beneficiary data. Ideally, each ABHA should be associated with a unique beneficiary, and the patching process should ensure this one-to-one mapping.

Steps to Reproduce:

1. Initiate the patching process for a single ABHA number.

1. Attempt to assign or patch this ABHA number to multiple beneficiaries.

1. Observe the incorrect association of a single ABHA number to multiple beneficiaries.

Expected Result:
Each ABHA number should be patched to only one beneficiary at a time, ensuring a correct mapping of ABHA to the beneficiary.

Actual Result:
The ABHA number is being associated with multiple beneficiaries

Acceptance Criteria:

1. Patching a single ABHA number should ensure it is linked to one beneficiary only.

1. If an ABHA number is already assigned to a beneficiary, it should not be available for patching to another beneficiary without explicit disassociation.

1. An error message or warning should be displayed if an ABHA is patched to multiple beneficiaries.

1. The system should validate that no ABHA number is duplicated in the beneficiary records.
