Handling internet disconnections


needs_upgrade

Recommended Posts

Hello guys!

 

My system cannot handle internet disconnections well. For example if a user will enter a customer?s payment, the system should do several functions like:

1. Add the payment entry to the payments table,

2. Subtract the payment from the accounts receivables,

3. Update the balance of the company?s bank account

4. Add the payment entry to the bank-trail table

 

But what if upon pressing the submit button, there has been an internet connection. There are instances where only functions 1 and 2 were finished. How can the system undo the inserts/updates made by functions 1 and 2 if functions 3 and 4 were not executed? - so that the user can repeat the process.

 

Thanks for your insights in advance
