Multiple IF condition

[Former Member]

Hi,

I've 12 fields to check(message mapping using IDoc segments) if anyone of them have value 03 then I want to read the associated field value into target field.

e.g.

if dar01 eq 03

move dat01 to target_dat.

elseif dar02 eq 03

....

elseif dar03 eq 03

....

elseif dar12 eq 03

move dat12 to target_dat

else

do not populate the target segemnt.

endif.

I've tried this using graphical mapping but it looks like a real mess, any idea pls...

cheers

Hi Taj,

Make use of Gloobal COntainer Object to set the flag. and then based the flag, do the rest of the mapping.

hi Moorthy,

I believe he wants to put it all into

one field - target_dat (so no need for container)

don't you think?

just <b>if, else if</b> and <b>concat </b>but I don't know where

the problem is...

Hi Michal & Moorthy,

I think I didn't explain the problem properly. I only need ONE of the 12 fields which contains value 03, I don't need to concat all fields.

Hi Michal,

You are right, but if-else if will look very messy in the mapping editor.. As per my understanding ,his question is mapping is very confusing/messy..

Thats the reason I just given a hint of Container. SO that it will be easily readable..

Hi,

I still don't know what he needs - java code for if, else?

Hi Michal,

I'm new to XI therefore I wanted to know if there is alternative to ifelse condition of graphical mapping and yes it may be Java but I don't know Java either so any guide line would be greatly appreciated.

cheers

hi,

now we know what you need:)

>>>>if there is alternative to ifelse condition of graphical mapping and yes it

of course there is - you can connect all nodes to

a simple user function and put some java code inside:

http://java.sun.com/docs/books/tutorial/java/nutsandbolts/if.html

and this will generate your result

(very easy and it will look ok for sure

you can also use <b>equals</b> method (to work with strings)

if you just need this no need to use globalcontainer then

this is simple if else if in a simple user defined function - nothing more

hi,

you can try this code in your simple function

with all 12 inputs (I assume that you name the inputs dar01, dar02 etc and not a,b,c..)

String finalResult;

if (dar01.equals("03")) {

finalResult = dar01;

} else if (dar02.equals("03")) {

finalResult = dar02;

} else {

finalResult = " ";

}

return finalResult;

for simple user defined fucntions check out this guide:

Michal,

I've tried creating the simple user function but can you explain the argument count should this be equal to no. of fields I need to parse if yes then its max value is 10 and I need to check 12 fields and further 12(24 in total) are the associated fields which contain the actual value that I need to get to.
