Full error text: Column not found: 1054 Unknown column 'childsku' in 'where clause', query was: SELECT COUNT(*) FROM owd_catalog_product_super_link AS main_table

LEFT JOIN owd_catalog_product_entity AS child_table ON main_table.product_id = child_table.entity_id

LEFT JOIN owd_catalog_product_entity AS parent_table ON main_table.parent_id = parent_table.entity_id

WHERE (childsku LIKE '%bl%')

Built report first by creating model for catalog_product_super_link

function _prepareCollection() contains...

$collection = $this->_superlinkFactory->create()->getCollection();

$collection->getSelect()->joinLeft(array('child_table' => $collection->getTable('catalog_product_entity')), 'main_table.product_id = child_table.entity_id', array('sku as childsku') );

$collection->getSelect()->joinLeft(array('parent_table' => $collection->getTable('catalog_product_entity')), 'main_table.parent_id = parent_table.entity_id', array('sku as parentsku') );

function _prepareColumns() contains...

$this->addColumn( 'childsku', [ 'header' => __('Child SKU'), 'index' => 'childsku', ] );

When filtering on Child SKU column, error occurs.

Figured it out. Realized it was going back to find childsku which is not in actually in the table, and that it needs to read sku from child_table.

Added method to set the correct filter index to the column AFTER the addColumn method, as follows...

        'header' => __('Child SKU'),
        'index' => 'childsku',
