how to get short text of a exception thrown by abap rfc

[Former Member]

Hi buddy,

I use jco to communicate with backend, an abap function module will raise a exception. I can catch that exception,

The example exception is:

<b>Exception</b> <b>Short text</b>

Test This is exception test.

e.getKey() 

will return TEST.

Does any know how to get that short text "This is exception test." from the exception I caught?

Thanks

Hi Austin,

There are 2 methods to raise errors in function modules.

1) Using the raise Exception statement

2) Using a return structure like BAPIRET to populate the message details like type, error number, error text etc.

Generally method 1 is not recommended for any RFC/BAPI function modules because it causes the calling program to crash if the function raises an exception. Method 2 is the recommended way and is used in all standard BAPI's. ABAP programmers are advised to code RFC's as per method 2, but some times it would not be possible as the function would already be used and could be barred from changes.

But whatever method the RFC uses to raise an exception, web dynpro can handle it in the following ways,

Method 1) If the RFC raises an exception using RAISE EXCEPTION,

Dont catch Exception class in your code, instead do the following,

catch (WDDynamicRFCExecuteException e) {

wdComponentAPI.getMessageManager().reportException(

e.getLocalizedMessage(),

true);

Method 2) If the function returns the errors in the standard bapi return structure, you can do the following

IWDMessageManager MsgMgr = wdComponentAPI.getMessageManager();

for (int i = 0; i < ReturnNode.size(); i++) {

if (Types.indexOf("S") != -1

&& ReturnNode.getElementAt(i).getAttributeAsText("Type").equals(

"S"))

MsgMgr.reportSuccess(

ReturnNode.getElementAt(i).getAttributeAsText("Message"));

if (Types.indexOf("W") != -1

&& ReturnNode.getElementAt(i).getAttributeAsText("Type").equals(

"W"))

MsgMgr.reportWarning(

ReturnNode.getElementAt(i).getAttributeAsText("Message"));

if (Types.indexOf("E") != -1

&& ReturnNode.getElementAt(i).getAttributeAsText("Type").equals(

"E"))

MsgMgr.reportWarning(

ReturnNode.getElementAt(i).getAttributeAsText("Message"));

}

Hi,

It is returning from the BAPI.

Then it has one field status u can utilize in After executing

U can capture the field.

And check your filed based on some condition.

Get the status field is

Do u want to capture that field I will give the code and u can utilize.

Or otherwise u can go as Anil's advice.

Thanks,

Lohi.

Try

e.getMessage() or e.toString()

Hi Anilkumar

unfortunately

e.getKey()=TEST

e.getMessage()=TEST

e.getMessageText() =

e.getLocalizedMessage()=TEST

the abap guy just write the following code to raise exception:

raise test

should the abap guy do something else?

Best regards,

Hi Austin,

I think you need to do more on ABAP side while raising the exception .

Check the link below

Hi Anilkumar

my abap guy tell me that if he uses classed based exception then the function module can't be remote call:(

I have little knowledge about abap.

Hi

Even i don't have any knowledge on ABAP !!!

But i've found a link explains about two diferent ways of raising exceptions in functionmodules

1. RAISE except.

2.MESSAGE.....RAISING except.

Just try with the second option.
