In our client we have one scenario in Export Billing.
We made export sales order. After that we are doing Billing then we are taking profomo invoice.
Then it is going to Customs Duty clearance. After completed clearance. we doing PGI and again we are doing Billing.
Now My question is when we created first Billing document no and after custom clearance we made one more billing both the Billing number should be same.
For Ex: Before Customs Billing no is 5200000010.
After clearance they are doing PGI and Billing that number also it should generate same number
Is this is possible? means how?
