I'm using a scripting functoid in a BizTalk map. In a certain case, I want the destination element to be skipped (rather than empty).
I'm using inline C#. When I return null, the destination element is empty. Is there a way to make it skipped altogether?
Use a LogicalEquals functoid to determine if your input matches your case. Then map that output to a LogicalNot. Send the output of the LogicalEquals to one Mapping functoid (second input for Mapping will be the value of your field) and the output of your LogicalNot to another (same second input). Then map both of the value mapping functoids to your destination node.
Then, when your value equals your case, you'll send FALSE to the destination (instead of Null or Empty) and the node won't be output. Any other time, the LogicalNot will fire its Mapping Functoid and you should get your desired output.
Here's how I resolved it: (Please post an answer if you have a better way.)
Split the scripting functoid into two. The first one determines whether the destination element should exist at all and returns a boolean. The second one determines what value should be set in the destination (if any). Use these two scripting functoids as the inputs to a value mapping functoid.
Update: I didn't see Allen's similar answer when I posted this. I'll leave my alternative approach here in case it helps someone.

Is there any way to add an additional node to destination based on source field existence using normal BizTalk functoids or xslt should be used?
For example :
If source field exists then add new additional node to destination
Otherwise don’t add new node to destination .
I want to know whether this can be achieved with BizTalk functoids or xslt should be used .
Yes you can do this in a standard map.
Have the element defined in your destination schema with it's Min Occurs set to 0
Use one of the logical functoids e.g. Logical Existence that you link from the source element to the destination
And also a link directly between the source element and the destination element.
You can also use other logical funtoids like Logical String or Logical Numberic if the field may exist but not contain a value and you then don't want the destination element.
I have source schema contains an element of which maxOccurs="unbound".
I want to map this element to a destination element but its maxOccurs="1"
This case I just want to map the first occurrence of source element to destination element, and ignore the rest.
How can I do this?
I usually use the Iteration functoid where one input is the node, the other is a fixed value of 1 and map it through a value mapping functoid, the first input being the iteration functoid the second being the source element.
You can also do this using the Index functoid: https://msdn.microsoft.com/en-us/library/aa547297.aspx
However, the iteration method may be easier to use if you have many nodes to map.
I have a mapping with a input-schema and a outputschema. If I send a xml-file with two fields that are not provided with the schema the element fields are written out, but with empty values. I would like to that it didn't write the elements at all in the output file.
Is it possible?
Use a "Logical Existence" Functoid to only produce the element in the output when it is supplied in the input.
To do this;
a) Drag the logical existence functoid to the mapper surface.
b) Drag a value map functoid to the map surface
c) connect the element from the source schema to the logical existence functoid
d) connect the logical existence functoid to your value mapping functoid.
e) connect the element to your value mapping functoid
f) connect your value mapping functoid to the destination element to conditionally map to.
This says "when i have element X in the source, then map its value to element Y in the destination. otherwise don't perform the mapping".
Do the steps above in order to ensure that the functoid inputs are configured correctly.

I would like to know how to detect that a node is not present in the origin. I have tried hundreds of things with the logical functoids with no success.
The third case of this page is what I am looking for:

Thanks in advance.
You can use the Logical Existence functoid. If the element is missing from the source message, this functoid will return false.
If you need to perform some logic based on the element being missing (like map a default value to the output message), pass the Logical Existence functoid output to a Logical Not to return true, then connect the Logical Not output to a Value Mapping functoid with the second input set to whatever you want the default value to be.
The only way I have managed to do it in a map is through XSLT in a scripting functoid.
if it is an element use logical string.
if you want to check record or node then use logical string and connect it to any element under that node or record.
let me know if this works out for u or not.
I have a requirement in BizTalk map, where
I will map some elements from source schema to destination schema,where the values will be assigned to destination schema elements based on some condition.
If those values are not assigned, i need to send some default value (N/A).
My map is not One-to-One so that i can use a scripting functoid and send a default value, on top of that the destination schema is a flat file and in source schema i have to loop a lot.
So can any body give me some suggestion about "How to set a Default value to a Element in Destination schema if nothing is mapped" using BizTalk Map/some setting in schema.
What I have already tried is, I Opened the destination schema for all the elements I have set the value 'N/A' to a property -> "DefaultValue" which was there in the property tab but when nothing is mapped the default value is not coming. Instead the node itself is not created in the Output file.
Please see the Map below for a good understanding

Source Schema is a XML schema.
Destination Schema is a Flat file schema.
Now in the above map, in my source schema I am having a node called F4706 which will loop.
When the element "TypeAddressNumber" within the F4706 is "1", then I am mapping the remaining fields of that F4706 instance to "ship to" details in my destination schema
When the element "TypeAddressNumber" within the F4706 is "2",then I am mapping the remaining fields of that F4706 instance to "Reseller" details in my destination schema
When the element "TypeAddressNumber" within the F4706 is "3",then I am mapping the remaining fields of that F4706 instance to "EndUser" details in my destination schema
Now if I connect a Logical NOT functoid to the Logical Equal functoid and assign some default value, then the my destination node occurs Three times as one time the "=" functiod returns true one time and false other two times. But what I want is, if anything is there to map then map from "F4706" instance or assign the default value.
Find the INPUT File below
alt text http://www.biztalkgurus.com/cfs-filesystemfile.ashx/__key/CommunityServer.Discussions.Components.Files/13/5430.ip.JPG
The output I'm expecting and getting is :
alt text http://www.biztalkgurus.com/cfs-filesystemfile.ashx/__key/CommunityServer.Discussions.Components.Files/13/0724.curOP.JPG
Now if the Input file is like below :
alt text http://www.biztalkgurus.com/cfs-filesystemfile.ashx/__key/CommunityServer.Discussions.Components.Files/13/6403.otherIP.JPG
That is when I don't have a "F4706" node with TypeAddressNumber=2, I need to fill "N/A" in Reseller related nodes in my destination schema, which should look like below :

If you go and check the XLST which is getting generated, it is writing a xsl:foreach so if you use xsl:choose/otherwise conditions gets checked multiple times and my output nodes gets duplicated.
I also tried to use some global variable in XLST in First Loop and and second loop to access that and write the default value, unfortunately it doesn't work too. Because a VARIABLE in XLST is not a TRUE variable. I think its a CONSTANT.
How to accomplish this ANY help is highly appreciated.
Put two "Value mapping" (Label them "Incoming" and "Default") on the map and drag the output from both to your destination (you will get a warning at compile time).
Put a "Logical NOT" on the map (Label it "NoValue").
Put a logical evaluation (Existence, IsNil, Length) that suits your need, to evaluate if you have an incoming value, and drag your source field to it. (Label it "HasValue")
Drag the result to the "Incoming" and the "Logical NOT".
Drag your source field to the "Incoming".
Drag the output from "NoValue" to "Default".
Add a constant parameter to "Default", by double clicking and insert new parameter, that is your default value.
Hope you understand this mess :)
I believe you are essentially trying to control the creation of an output node based on some condition.
I have tried this for records (you are trying to do this for elements, so I believe this should work for that as well).
I had connected the output of the Logical functoid to the record and the record was created only if the logical functoid returned true.
For default values, you are doing it the right way by putting the default value in the property grid for Schema element. So if nothing is mapped to this element, you will see in the xsl file that the element with the default value is generated.
