I am using Magento 2.3.2. When i am tring to add Customer Group Price for child product of configurable products in admin panel then i am getting below error when save the product:
SQLSTATE: Integrity constraint violation: 1062 Duplicate entry '16092-1-0-30.0000-0' for key 'UNQ_6D3040166530765494A77D7288801D79', query was: INSERT INTO
percentage_value) VALUES (?, ?, ?, ?, ?, ?)
but it's working for Simple Products as expected.
I am not able to understand why i am getting this error.
Once i have truncated that table but still getting Integrity constraint violation: 1062 Duplicate entry
