Return MIGO

Dear SAP GURU,

An issue regarding the return MIGO done without excise by our store department.

Actually they made a MIGO with Excise but realized that the excise amount was wrong. So they tried to make a return MIGO for the same but created a return MIGO without Excise.

Now I need to confirm that where will this Excise affect and how can we get rid of the same.

Thx In adavance
