query

select company_code, item_code, item_description, product_line,
udf_item_width, udf_item_length, sales_unit_measure, ''as mat_type from
mas_combined_item_master where company_code='BUR' or company_code='SNJ'
or company_code='EBC' and udf_edb_managed=''
and item_code LIKE 'S-%' order by item_code;

comment

Second column is item_code...why are these items in the results.
Expecting the query to return results where the item_code

starts with "S-" and includes any othervalue past "S-"

Based on your description, your query is not correct; you should rewrite it, likely using parenthesis to define your actually desired value expression.

See also https://www.postgresql.org/docs/13/sql-expressions.html#SYNTAX-EXPRESS-EVAL

This may or may not be what you intended:

SELECT company_code, item_code, item_description, product_line, udf_item_width, udf_item_length, sales_unit_measure, ''as mat_type
FROM mas_combined_item_master
WHERE (company_code='BUR' OR company_code='SNJ' OR company_code='EBC')
AND udf_edb_managed=''
AND item_code LIKE 'S-%'
ORDER BY item_code;
