SysOperations service table filter at runtime

Hi everyone,

I'm writing a SysOperations service which utilizes an AX query. The query joins the MCRHoldCodeTrans to SalesTable to CustTable tables. I have ranges defined for MCRHoldCodeTrans and CustTable in the query. The "service" works in that the dialog pops up, the two ranges I defined in the query are showing as filters on the dialog. The issue though is SalesTable is not an available option for filtering when I go into "Records to include" of the dialog. The relation on the SalesTable in the query is to MCRHoldCodeTrans > SalesTable which should be correct. Maybe the cardinality is off (OneToOne vs OneToN)? 

Thank you!
