Separate autocomplete rule from recruiting

Content:

Hello all,

we have an autocomplete rule on "Worker Assignment" to show an error message, if two field are not populated, thus mandatory. This error message should only be shown for specific Business Units and specific Assignment categories.

The rule works perfectly, however this error message triggers also in the recruiting module. We tried to add some conditions by calling the HCM Params for some workflows or also by adding a condition to check the users' roles. Unfortunately this has not yet solved the problem.

Is there a way to separate the autocomplete rule from recruiting, in order to work only on the assignment pages in core?
