Dear Amit sir,
In tally negative stock just notifies but not restricts the billing. so i want to restrict the billing if there is negative stock.

 

Thank u for the help

 

Amit Sir,

If we use control then first item gets skipped then if we go backwards and again enter item then it is controlling, can you suggest why it skips for the 1st time and again go backwards and select the item it get controlled, any solution.

Thanks
