MB1A (Goods Issue to Reservation)

Hi,

We are having a specific requirement regarding our inventory

controlling. As per our client requirements we have created a new transaction code ZMB1A (Goods issue against reservations only), and we want to arrest/Deactivate the "To reservation" Push button, in the standard transaction code MB1A.

Please inform me, how can I deactivate this push button in our

production client.

Looking forward for an early response,

Best Regards

Jeya
