changing comma (,) into dot (.) when data transfer.

​We have an issue in the data transfer from the Inventory Part window (frmInventoryPart)  to the Part window (frmPartCatalog) 

If we defined part number with a comma (ex: TEST,Part01) it converts to a dot (.) symbol (ex: TEST.Part01) when transferring data. The result was not populating the Part window and it shows as empty.

The reason for this is its defined decimal Symbol as comma (,)

So can we instruct the customer to change it to dot (.)?
will it affect other functional behaviors of the application?
