Using Mvt type 124

Hi ,

I received goods from vendor and due to some issue we posted the material using MVT TYPE 103 which converted the same as GR Blocked stock.

Now I have to return the material back to Vendor. I tried using Mvt type 124 - which says return delivery from GR Blocked stock,

when i am trying to post the do MIGO using this mvt it is asking for the reason for movement , when looking for the movement reason i do not see any reason , and system does not go further without the reason......

Please some one help me with solution and also suggest me the right method if I am wrong ..

Thanks,
