L3 720 Error in Transfer order creation

Hi,

I am creating a transfer order using the BAPI 'L_TO_CREATE_DN ' but the TO creation is unsuccessful asI am getting the error message '2 Step picking relevance will be removed since no relevant group'.

But using LT03 transaction if transfer order is created the same error message is shown as Warning message.

Could you please help me creating TO ?

Thanks in advance,
