In this post I am just going to describe the how we can suppress all errors or some particular errors using error handling.

Suppressing all errors

Suppressing All Errors is very easy, all you need to do is just have blank catch statement for example

try
{
//some code
}
catch(e)
{ ; }

The above mentioned code will result in suppressing of all errors which is never recommended as it can lead to data integrity issues.

Just think user is entering some data and tries to save a record and the script written in write record results in some error. Now, user won’t see any error messages and he will think he has entered record properly where as it is not the case. So, we should never use this, until and unless we are pretty sure of what we are doing.


Suppressing particular errors:

There are some cases in which we know that a particular type of error can occur which is not going to affect the functionality and we would like to suppress that error. That can be done by the following the below given steps:

  • Replicate the error in Application.
  • Note down the text of the error (when the pop-up with error message is shown press CTRL+C and the error message will get copied)
  • Every error has an error code associated to the text, note down the error code in the error message.
  • For example
    “A script failed to get the value for field Revision Number because the field was not active.(SBL-EXL-00119)”
    for the above mentioned error the error code is SBL-EXL-00119.
  • Now the below mentioned code will suppress above mentioned error and give a pop-up if any other type of error occurs

    try
    {
    //some code
    }
    catch(e)
    {
    var errtext = e.toString();
    if(errtext.indexOf("SBL-EXL-00119") == -1)
    TheApplication().RaiseErrorText("Error Occured");
    }

To handle multiple errors you can have switch statement and basically do whatever you want to.

Well, this is the end of Error Handling series hope it would have helped you all. Post your comments and question in the meanwhile I will start working on another topic :)

    Hi Neel,

    Thanks for the post…could you please explain regarding the -1 in the if statement..

    thanks in advance..

    indexOf function returns -1 if the specified string is not found and if it found then it returns the starting point of the string

    So, -1 here means some other error has occured so, show the error message and in case if it contains the error message we want to suppress it will return a positive number denoting position of error code hence no error message and the error is suppressed.

    i have a question, I have seen at times that developers write

    catch(e)
    {
    Throw(e);
    TheApplication().RaiseErrorText…..
    }
    I belive that in the above code Raise Error wont get fired..since throw e will cancel the opeartion there..
    Help me understanding it.

    hi all,
    actually as siebel best practice it’s advised to cache business services
    and i did so

    but the problem that in our system there’s a BS to make Data Quality before update or insert

    invkoing this BS results in populating the Error Message Property in the workflow

    for Example in Data Quality
    if(name == “”)
    TheApplication().RaiseErrorText(“Error 100″);

    the Error Message property is then input for another business service to handle the error

    The Problem
    ===========
    due to caching the Error Message property is appended every time
    and error codes is accumlated

    the Question
    ============
    is there any way to clear it (without Remove Business Service Caching)

    see this link maybe it helps to understand the problem

    Hi Neel,

    I would like to know, take a scenario if there are ten lines of code in TRY block and i know there would be an error on line 5 and i need to suppress the error and continue with my code execution. How should i encounter this scenario?

    Thx

      If you know there is error on line 5 then why don't you fix it :)

      but there is no way in eScript to resume from where error occurred. You can suppress error but the control will go to finally clause or catch clause.

      This thing might be possible with a combination of eScript and workflow but I have never tried that.

        Hi Neel,
        what about a try/catch/finally inside another try/catch/finally?

        Let’s say I have a piece of code and inside this piece of code there are some lines which “might throw an error” … so could we pack these lines into a seperate try statement? If it fails, the “outside” try block will still continue, no?

    Hi Neel,
    thanks for this excellent series of posts. I have an addition to this one. I have tried to catch errors using the method described above (a switch statement in the catch block, catching the SBL-xxx codes) but it did not work. After a while I found that we can also use the e.errcode which seems to be individually for a certain error as well.
    So I tried something like this:

    catch(e) {

    if (e.errCode == ’22045′) { //same values for name, location…
    var accname = accBC.GetFieldValue(“Name”);
    accBC.SetFieldValue(“Name”, accname + ” *CHECK*”);
    accBC.WriteRecord();
    myfunction(); // run the function again
    }

    else if (e.errCode == ’22195′) //record has been modified since it was retrieved
    myfunction() // run the function again …

    else if (e.errCode == ’22709′) { //fill in all mandatory fields
    if (accBC.GetFieldValue(“Street Address”) == “”) {
    accBC.SetFieldValue(“Street Address”,”empty”);
    accBC.WriteRecord();
    myfunction()
    }
    else if (accBC.GetFieldValue(“Postal Code”) == “”) {
    accBC.SetFieldValue(“Postal Code”,”empty”);
    accBC.WriteRecord();
    myfunction()
    }
    else if (accBC.GetFieldValue(“City”) == “”) {
    accBC.SetFieldValue(“City”,”empty”);
    accBC.WriteRecord();
    myfunction()
    }

    }

    else
    WshShell.Popup(“This is e.errcode: ” + e.errCode + ” – This is e.toString: ” + e.toString());

    //throw e;

    } //end catch

    Hi Neel,

    I am silent admirer of your posts. I am posting for the first time, please keep enlightening the Siebel community.

    Regarding this post, why not make the field Force Active on the Field level to get rid of this error!!!

    Regards,
    Shiv

    • Anonymous

      Hi Shiv,

      Thanks for the compliments. You are right we can make the field force active to avoid this error but there are two things I would like to say:
      1. the code in the above post is just to demonstrate an example and not to fix this particular type of error.
      2. Making field force active is not the solution of the this problem ideally we should be doing an activate field before doing a get field value which will eliminate these errors.
