    Also your query is wrong in a sense that you are doing addField calls, but AX automatically adds all fields for you. You only need to add specific fields, if you have cleared the field list beforehand.

    Also you should consider using SysQuery::findOrCreate* method as a good practice to avoid adding duplicate datasources, ranges, whatsoever in the future.

    Finally, check the generated query as Martin suggested in order to be sure the data you are expecting would show, like you are not missing records for the value you are trying to filter for, you are also in the correct legal entity (company), there are relations correctly defined between the tables, and finally exprimenting with the fetch mode.

    Can you explain your problem, please? Fixing an unknown problem is quite difficult.

    I strongly recommend you look at the query you generated and compare it with what you intended. Call qbdsCustInvoiceJour.toString() to get the SQL-like query string. You'll probably need to add .fetchMode(QueryFetchMode::One2One) on the child data sources to see them there (or to restructure your query to use CustTable as the root datasource).

    By the way, make sure that your GatePassLine table has a corresponding relation.
