Sysytem says that EndDate should be greater than StartDate.Function looks like true.What is wrong?
3.Module 3.Task


Function ProcessIncomeDocs(StartDate = Undefined, EndDate = Undefined) Export

Message = "Error executing ServiceSrv.ProcessIncomeDocs";
EmptyString = "";
If StartDate <> Undefined Then
If TypeOf(StartDate) <> Type("Date") Then
Return Message + Chars.LF + "StartDate parameter has to have the Date type";
else
Return EmptyString;
EndIf;

EndIf;

If EndDate = Undefined Then
EndDate = EndOfDay(CurrentDate());
Else
If TypeOf(EndDate) <> Type("Date") Then
Return Message + Chars.LF + "EndDate parameter has to have the Date type";
else
Return EmptyString;
EndIf;
EndIf;


If StartDate <> Undefined Then
If EndDate < StartDate Then
Return Message + Chars.LF + "EndDate has to be greater than StartDate";
else
Return EmptyString;
EndIf;
EndIf;
EndProcedure

Hi Mesut,

Your function does NOT check anything but the very first condition (if the StartdDate parameter has the Date type). As soon as this condition is successfully checked, the function finishes working, because of this string:

Return EmptyString;

Yes,The problem has solved.

But System says one line should be added to detail tabular section.I have added a line Detail Tabular section.
What is the  problem?

I have checked and saw the error: incomes=<?>documents.income.select(satrtdate,enddate) , variable is not defined.

I can not understand?

Mesut, I wanted you to:

• Set a breakpoint in the beginning of the ProcessIncomeDocs procedure
  
• Run the application and click the Run The Test button
  
• After the debugger stops the execution at the breakpoint, trace the procedure step by step and see what it does and what it does not do
  

I have done what you say yesterday,I couldn't see the problem,but I see the problem now.Because of I put Return,the code jumps over Incomes code.I made comment line the Return code and the problem has solved.

Thank you very much!
