Issue:
Unable to save a product in the backend of Magento, with the following error message displayed, and logged in exception.log and system.log:
The stock item was unable to be saved. Please try again.
This could be an indexing issue, or a database permission issue. This is common when performing a migration or importing a database from another source.
Possible Solution(s)
1) Perform a reindex:
php bin/magento indexer:reindex
2) If indexing didn't fix the issue, create a dump of the database and check that there is no definer set:
mysqldump --single-transaction -u example -p example_magento --triggers > example_magento.sql grep -i DEFINER example_db.sql
If it has a definer set, the following would be seen (example):
15544:/*!50013 DEFINER=`some_other_example_user`@`localhost` SQL SECURITY DEFINER */
You could then either replace the incorrect user or just remove the definer altogether, as in the example below:
cat example_db.sql | sed -e 's/DEFINER[ ]*=[ ]*[^*]*\*/\*/' > example_db_without_definer.sql
Or just create a new dump of the database, removing inline using sed:
mysqldump --single-transaction -u example -p example_magento --triggers | sed -e 's/DEFINER[ ]*=[ ]*[^*]*\*/\*/' > example_db_without_definer.sql
Then reimport the database:
mysql -u example -p example_db < example_db_without_definer.sql
