Can't assign DataSource to object 0COORDER

Dear All,

when I try to assign DataSource 0COORDER_ATTR and 0COORDER_TEXT to source system I get message:

"Mapping between 0COORDER_ATTR EHTCLNT230 0COORDER is inconsistent'

and at the popup window:

"The DataSource is already assigned to InfoSource 0COORDER_ATTR"

I can see only 0COORDER_0103_HIER DataSource assignement. What should I do?

Regards,

Maciek
