I am trying to build my own excel export template because I have a changing number of columns with changing properties as headers. I am building the template in a microflow based on the columns I want to see in the excelsheet by looping over the columns and translating them in mxcolumns with mxpaths. The creating of the mxsheet works, but the creating of the columns fails.  The select statement is not build correctly in the java action from the XLSreport module; GenerateExcelDoc . Can someone point me to a solution. I think I put in the wrong information somewhere, but with debugging I cannot find where. This is the error I get: ERROR: missing FROM-clause entry for table "a2system$filedocument"   Position: 474 com.mendix.systemwideinterfaces.MendixRuntimeException: com.mendix.core.CoreRuntimeException: com.mendix.systemwideinterfaces.MendixRuntimeException: com.mendix.basis.connectionbus.ConnectionBusException: An exception has occurred for the following request(s):      InternalOqlTextGetRequest (depth = -1): SELECT a03ec4cce.__UUID__ AS __UUID__0, a03ec4cce.__UUID__ AS __UUID__1, a03ec4cce.__UUID__ AS __UUID__2, a03ec4cce.__UUID__ AS __UUID__3  FROM "KweekAdministratie"."WaarnemingExportExcel" AS a03ec4cce   JOIN "a03ec4cce"/"System"."owner"/"KweekAdministratie"."WaarnemingExportExcel" AS refobject ON refobject/ID = 60798594969502997    ;     at com.mendix.basis.actionmanagement.ActionManagerBase.executeSync(ActionManagerBase.java:156) Caused by: com.mendix.core.CoreRuntimeException: com.mendix.systemwideinterfaces.MendixRuntimeException: com.mendix.basis.connectionbus.ConnectionBusException: An exception has occurred for the following request(s):      InternalOqlTextGetRequest (depth = -1): SELECT a03ec4cce.__UUID__ AS __UUID__0, a03ec4cce.__UUID__ AS __UUID__1, a03ec4cce.__UUID__ AS __UUID__2, a03ec4cce.__UUID__ AS __UUID__3  FROM "KweekAdministratie"."WaarnemingExportExcel" AS a03ec4cce   JOIN "a03ec4cce"/"System"."owner"/"KweekAdministratie"."WaarnemingExportExcel" AS refobject ON refobject/ID = 60798594969502997    ;     at com.mendix.util.classloading.Runner.doRunUsingClassLoaderOf(Runner.java:36) Caused by: com.mendix.systemwideinterfaces.MendixRuntimeException: com.mendix.basis.connectionbus.ConnectionBusException: An exception has occurred for the following request(s):      InternalOqlTextGetRequest (depth = -1): SELECT a03ec4cce.__UUID__ AS __UUID__0, a03ec4cce.__UUID__ AS __UUID__1, a03ec4cce.__UUID__ AS __UUID__2, a03ec4cce.__UUID__ AS __UUID__3  FROM "KweekAdministratie"."WaarnemingExportExcel" AS a03ec4cce   JOIN "a03ec4cce"/"System"."owner"/"KweekAdministratie"."WaarnemingExportExcel" AS refobject ON refobject/ID = 60798594969502997    ;     at com.mendix.basis.actionmanagement.ActionManagerBase.executeSync(ActionManagerBase.java:156) Caused by: com.mendix.basis.connectionbus.ConnectionBusException: An exception has occurred for the following request(s):      InternalOqlTextGetRequest (depth = -1): SELECT a03ec4cce.__UUID__ AS __UUID__0, a03ec4cce.__UUID__ AS __UUID__1, a03ec4cce.__UUID__ AS __UUID__2, a03ec4cce.__UUID__ AS __UUID__3  FROM "KweekAdministratie"."WaarnemingExportExcel" AS a03ec4cce   JOIN "a03ec4cce"/"System"."owner"/"KweekAdministratie"."WaarnemingExportExcel" AS refobject ON refobject/ID = 60798594969502997    ;     at com.mendix.util.classloading.Runner.doRunUsingClassLoaderOf(Runner.java:36) Caused by: An exception has occurred for the following request(s):      InternalOqlTextGetRequest (depth = -1): SELECT a03ec4cce.__UUID__ AS __UUID__0, a03ec4cce.__UUID__ AS __UUID__1, a03ec4cce.__UUID__ AS __UUID__2, a03ec4cce.__UUID__ AS __UUID__3  FROM "KweekAdministratie"."WaarnemingExportExcel" AS a03ec4cce   JOIN "a03ec4cce"/"System"."owner"/"KweekAdministratie"."WaarnemingExportExcel" AS refobject ON refobject/ID = 60798594969502997    ;     at com.mendix.connectionbus.RequestAnalyzer.doRequest(RequestAnalyzer.java:54) Caused by: Exception occurred while retrieving data.
