If a voucher of extra amount is getting triggered during an update, it is likely that the client is using both Emist Pro and Emist applications for Hire Slip creation and voucher updates.
This dual usage can lead to duplication or mismatched data during updates, causing vouchers with incorrect amounts.

Resolution:

To avoid this issue, ensure that only one application is responsible for Hire Slip creation:

• Revoke permission for the Hire Slip form in the Emist Application.

• Continue using Emist Pro as the sole source of hire slip creation and voucher updates.

This ensures consistent source tracking and eliminates redundant voucher creation.
