Warehouse - TO confirmation

Hi,

While doing TO confirmation the system accepts decimal values also.

Ex. If 10 PCS are done MIGO and while TO confirmation if I enter 5.5 PCS the system accepts and post the confirmation and also shows the warehouse stock in LS24 with decimal value.

Can you explain why SAP accepts decimal stock for PCS also? Can we set a error msg when we wrongly enter the value in decimals.

Regards,

Jagan
