Setting Up Manual & Automatic Payment Program

I am doing a project in my institute. we are facing a problem in running a automatic payment program.  Suppose I have a balance of Rs 100000 in my bank account and today I am running a Automatic payment run.  Total payment of the run are Rs 150000.   So when I run Automatic payment run it is not giving any error message. What to do with this problem. 

In my point of view we have to create validation. And link between bank account and payment method.  If the balance is less than the automatic payment amount the run should be stopped .

The Automatic Payment Program does not check the Balance of your Bank Account.(GL A/c. Bal.) 

What it does check is the min & max amounts that you have maintained in your customisation. 

In  FBZP Transaction (type in easy access screen), you have to maintain the config for your automatic payment runs. 

In Bank determination (in FBZP), you have to fill in the available amounts  for  each Bank. This is the maximum amount up to which payments will be generated by the Auto. Pay. Run. 

So if you want to ensure that on any single day the payment run does not pay more than bank balance, you have to update on a daily basis available balance to match with your bank balance . 

In SPRO you can find the customisation for A P Run, but FBZP is the old transaction for the same thing. Plus it lets you do all the related customisation, in one place. 

As far as I know, there is no direct way of linking your GL account balance to the A P Run.
