Hi,
How are you using the same material code when you are performing a repacking operation for the material code which you have procured externally. I think Ideally you should use a different material code for sales. This way you can easily find a solution to your problem. i.e. you will have 2 different material codes and you can use separate stock putway and removal strategies for the same.
Even going with your existing design you putaway is happening in your FX1 storage type which will be controlled by your stock putaway indicator in your material master (helps to determine the correct storage type in your storage type search sequence) then a repacking operation is performed and stock will be moved to your FPS storage type so in this case it will be a internal movement so by using a special mov. indicator or by using storage location reference (diff storage loctn) functionality you can putaway the material to FPS (even though putaway indicator is the same) and finally using the stock removal indicator in your WM - 1 view removal will be done from your FPS storage type.
Hope it is clear.
Thanks n Regards,
