Can we have error handling mechanism while updating a custom table in update task while saving SO?

Hi All,

I have a requirement where I need to update a custom table while changing the sales order with latest CDHDR change number for the current performing changes in SO.

In order to achieve this , I have created an implicit enhancement at a place where CDHDR got updated with latest change number and i have called a custom function module to update my Custom table with the above latest change number in update task.

Query:

If in case , Sales order is changed and saved successfully but Custom table is not updated,

How to handle this scenario and also how to update the custom table with those missed entries ?.

Please let me know if this scenario be handled by any approach.
