error in adding field

Hi Gurus,

I am trying to add a field from the commn structure to the extract str for 2lis_11_vahdr ds by clicking on maintenance and dragging the field from right to left. when i confirmed entries it reports an error stating " entries for pplication 11 still exists in the extraction queue ". i also deleted the setup tables in lbwg but still the error persists. i dont have a clue here. do help me out.

bye,
