    You need to show us full code along with other details like let's say how the standard is built or any table relations edt relations etc should be specified.

    You can refer to these two blogs, which explain the causes of this error and the corresponding solutions:
    jkmsd365fo.wordpress.comThis error is appearing because of adding a Lookup method for a form control which already having the EDT Relation with Table reference. Now System trying to open the same lookup with “Our lookup query logic” as well as “EDT Relation” . So it is throwing this error.
