Making a Deliberate Fail in Graphical Mapping

[Former Member]

Hello Friends,

We have a transformation logic in which we have to deliberately fail a mapping.

The Logic is

1) Concatenation of 3 fields.

2) After concat if length>9,make it boldFAIL.

If the len<=9,then pad as many zeros to make the length 11 and the add a constant 5 at the beginning

Now, how do we go about FAIL part of the mapping.

Hi,

You can achieve this by just a single line of code in UDF.

After check for length > 9 in if then else boolean function in graphical mapping.

call a UDF with following code.

 
public String callException(String var1, Container container) throws StreamTransformationException{ 

throw new RuntimeException("Length Greater than 9") ; 

return null; 

} 

If you want to display some message in the trace. you can use the trace object:

 

AbstractTrace trace = container.getTrace(); 
trace.addInfo("callException: Length greater than 9.");

Hi,

Please go through the following link which is exteremely useful:

This link should definitely solve your issue.

Thanks all for the replies.

One more query.

"On availability of a CO_PA record from source, 30 CO_PA records need to be populated for E2BPACKEC segment in the Target".

How can we do this?

Hi Sanjay,

can you explain your requirment more clearly?

Hi Deepak,

The requirement is that there is a segment for CO PA data in a file. there are 3 segments overall. Header, Detail and COPA.

So, If the COPA segment has data in the source file, then in the Target. The segment E2BPACKEC in the Target IDoc has to occur 30 times in the Target.

Any good?

[deepak_shah]

Hi,

What is the occurence of segment E2BPACKEC. Is it 0..1 or 0...unbounded?

If it is 0..1, then you can duplicate the segment E2BPACKEC 30 times and put a condition that the node will occur only when there is data for COPA segment.

it is is 0 ..unbounded, youhave to write a udf.

Regards,

Deepak.

Thanks Deepak,

Yes I am aware of the fact that we need to write an UDF for it.

Could you help me out on it please?

Hi,

Here is the logic.

Copa --> exists --> Generate30Times --> Output.

UDF Generate30Times Code

//Queue type UDF

if(input[0].equals("true"))

{

for (int i=0; i<30;i++)

{

result.addValue("");

}

}

Hello,

Alternatively, you can use this mapping:

source --> lenght --> greater --> createIf --> RootNode
constant:8 ------------> /

Since it would be failing at the Root level if the condition is not met, you can use the second logic for the actual node

If the len<=9,then pad as many zeros to make the length 11 and the add a constant 5 at the beginning

source -------------> add --> target
constant: 500000000000 /

Hope this helps,

Mark

FAIL means>

you want to stop mapping execution , with red flag in MONI

clarify this point;

Yes.

That would be the requirement.

hi,

create a UDF and put this in

throw new StreamTransformationException("test");
