graphical mapping if else condition

[Former Member]

Hi Friends,

What is the different between if and IFs in graphical mapping? I have a requirement where I have 3 source fields Src1 , Src2 , Src3. Target field Trg1.

I need to check if Src1 ( String) is not empty then trg1 = Src1 else if Src2 is not empty then Trg1 = Src2 else if Src3 is not empty then Trg1 = Src3.

How can I acheive the above ? Please advice.

Thanks,

Teresa

Hi,

Use the mapping as below:

You can use different function instead of exists() if required (for example if you value always exists, but sometimes is empty, then use equals empty). And of course use your own fields instead of Name1,2,3.

Hope you'll find this useful,

Hi,

The difference between IF and IFs is that IFs works like an if statement. that means that first the condition is evaluated and based on that either the IF or the ELSE branch is evaluated.

In the case of IF all the branches get evaluated.

In your case you can safely use any of the two blocks.

whats the output in case when all the input fields dont have any value??

chk this UDF :

if(a.length()>0)
{
return a;
}
else if (b.length()>0)
{
return b;
}
else if(c.length()>0)
{
return c;
}
else
{
return "No combination exist";
}

Hi Teresa,

By using SDN search button with "IFS", in less 2 min, you should find by yourself the answer.
