Hi guys, I’m a new appsheet user. I have some errors with my new app:

“Table ‘Trangtinh1’ has an implicit (RowNumber) key – if multiple users insert or delete entries concurrently, data loss can occur. Updates may apply to the wrong record or could fail entirely on some data sources”

How should i do to fix this???

Hi @Minh_Duc_Phuong, the above message is a warning message,indicating that you may wish to assign a unique explicit key for each record of the said table…

(RowNumber) key is a system assigned key when app creator does not assign a key of her/his own.

Please go through the article mentioned below to
