Hi Vikram,

Read ACL must be configured for view access to any table data.

Apart from that, there is one more thing that puts read restriction in Business Rule. Please check if that table has any "Query" type Business Rule. This type of business rule runs each time you try viewing data on a table and if the condition mentioned in the BR does not match, then it will simply not display any record and also it will not indicate any error message. Please check and let me know if there is any such rules.

Thanks!
