Navision 2017(CU7), tableType = ExternalSQL, REGISTERTABLECONNECTION error

Hi All,
I have one question for inserting externalSQL table.
I have to add one view from another sql database into Nav 2017(CU7) for CRM Connector, becouse I have some issues with NULL values in custom CRM view in SQL database.
I created simple table with this setup:



On sql databse is it in database xxxx, and view has name dimSYSTEMY_CRM_w
Than I prepared page list on this table and insered code into onInit and openPage trigger to call codeunit function for table registration.
Code looks same like core in function IsCRMIntegrationEnabled in CU 5330:
function:
IF NOT HASTABLECONNECTION(TABLECONNECTIONTYPE::ExternalSQL,GETDEFAULTTABLECONNECTION(TABLECONNECTIONTYPE::ExternalSQL)) THEN BEGIN
IF lreCRMConnectionSetup.GET THEN;
IF NOT ISNULLGUID(lreCRMConnectionSetup."User Password Key") THEN
IF lreServicePassword.GET(lreCRMConnectionSetup."User Password Key") THEN BEGIN
UNREGISTERTABLECONNECTION(TABLECONNECTIONTYPE::ExternalSQL, 'xxxx');
REGISTERTABLECONNECTION(TABLECONNECTIONTYPE::ExternalSQL,'xxxx',STRSUBSTNO(ConnectionStringFormat,'yyyy','xxxx',lreCRMConnectionSetup."User Name",lreServicePassword.GetPassword));
SETDEFAULTTABLECONNECTION(TABLECONNECTIONTYPE::ExternalSQL,'dimsystemy_crm_w');
END;
END
IF I call this function separately, navision register table without any errros (I can debug it). But if run Page List of this table (my function is on onInit and onOpen page trigger), navision will show error, that I have to use commnad RegisterTableConnection or New-NavTableConnection in cmdlet, before i open this page.
I cant use debugger, becouse navision dont stop on break point a application will drop down with debugger.
I wanted to try use New-NavTableConnection, but I not have it in cmdlist.





Thank you for answers...,
George
