I have a form in which I enter various components with their weight and material number.
Is it possible that powerapp also writes if I have entered a material number twice?
Example: 384-345 8kg324-233 9kg384-345 //This number already exists//
Assuming that you are using SharePoint Online as database, if you have configured the column to allow only unique values, the submit of the form will fail.
If you want to validate the data before submiting the form, add a LookUp looking for that material number. If the result is blank, the material number does not exist in your data origin.
