Unique batch number in MB1B with mov type 344

Hi Experts,

We have the following requirement from our client, kindly share your valuable information.

When we do transfer posting by using MB1B with movement type 344, system allows entering different batch numbers in Batch field and Issue batch field

For example:

Batch number in Batch field: ABC

Batch number in Issue batch field: XYZ

How do we restrict the system not to allow this functionality?

Thanks in advance

VNR
