Hello Munna,

Try to map exists with the node of the destination field if its occurance is 0 to unbounded.If the field in the source exists then the target element will be produced otherwise not.

Hi Munna,

Try Creating a UDF in your mapping name it like: "Create"

Paste the below mentioned code in it

========================

String str = a;

if(str != null && str.length()>0)

return "true";

else

return "false";

========================

2) Save this function .

3) Now Map like this

(Source Node->UDF Create)->Check if it returns a string "true"--> if yes Map it with source node->add this in the "then" of an "if with out else"---->Target node.

4) Test now in testing tool in Message mapping.

Try it.

it will work

regards

Pl: reward points if it worked

No need for UDF.

Just use IfWithoutElse and as input use a compare (using EqualS) between the field you want to check and an empty string (using constant).

there is exists node function in graphical mapping.

Source Node --- Exists ---target Node

Hi munna,

Use exists to determine whether a particular source field exists in the XML instance to be processed in source system. If it exists() returns the value true, if not it returns the value false.

Hello Munna,

You can achieve this bu using inbuilt functions EXISTS and IF block.

Please incorporate these functions in your message mapping for the optional fields .

HI,

As explained above in message mapping , just map the required fields/required segments , next need not to disable or remove in messamapping in target structure , if the receiver side segment /element is mandatory i mean red color then you should map with a value / or empty constant or right click and disable

if it is not mandatory i mean if it is optional then do not map thats all it will not in resultant structure ..

But display purpose all the rest of 100 segments will display only ,

if you want to hide , we have one filter symbol in mapping editor click on that symbol , all the unmapped elements or segments will be hidden.

if you want to disply again click on filter symbol again.

Hi Munna,

Map only those fields which u want to put in XML file....from IDOC structure to File structure in Message Mapping.

Hi,

right click on the target segment in the message mapping

and <b>remove</b>

this will remove this segment

Hi

Just right click on segment during mapping and click on disable/remove field to remove the node.

Do not map the source fields to the target in your mapping which you do not want to be sent.
