Interface Determination Conditions

[Former Member]

Dear All,

I have 2 different mappings. My source XML contains a "NAME" field. If this name field is having some value then mapping 1 should get executed. But if "NAME" field does not exists in source XML then mapping 2 should get executed.

Note that in second condition NAME field itself is not there in Source File.

As I want to change mapping depending upon source payload, I am using Interface determination. Here I have added two interface mappings. But I am not able to give the conditions. I have already followed links from Help.Sap.com.

Can anybody will help me to solve this?

Hi ALL,

I dont think that any condition specification option is available in Interface Determination, condition specification option is there in RecieverDetermination but not in Interface determination

If you specify multiple mappings in Interface Determination, you get the condition option. Here depending upon XPATH or context Object you can specify the conditions.

hi gouri,

in ID--> interface determination give two inbound interfaces. u wil then have an option to specify the condition. the left operand can be a context object or xpath pointing to ur specific field of source structure. use this to check if the node/element exists or not. if it exists then ur 1st mapping will be executed.

also see this:

Thanks Latika.

I have already tried this. I am doing the same thing. First condition is, NAME field from source (XPATH) is equal to blank and second condition is Not equal to blank.

But it is not working. For blank I have not specified anything. Do I need to specify anything?

I tried with " " or ' '. But still it is not working.

If I check my mapping programs with payload from SXMB_MONI, it gives correct output. That means the conditions from Interface determinations are not working.

hi gouri,

from ur first post i infer that u want to check whether the "NAME" exists in source structure or not. rite?

if so, use 'EX' operator. its checks the existence of a particular element. u may leave the right operand blank.

refer this:

hi Gouri,

Have you check this blog by shabharish.

Ya I tried with EX Operator too. But What I can do is first condition will be XPATH EX blank. But what abt second condition?

-Gouri

[Former Member · Accepted solution]

Hi Ramesh,

I checked that blog. It specifies about EX Operator. which tells that field exists or not. I want to specify a condition which talks about DOES NOT EXIST.

I mean to say Opposite to EX. Just like for equal to we have not equal to.

hi gouri,

Have you tried NULL for comparison.

hi gouri,

there is no operator as 'not exists'. and this is logical also coz when u give XPath for NAME as left hand operand, it means that NAME is present at runtime at first place.

for second condition then i suggest, u compare any other element/flag if its value depends on the existence of NAME

[nisarkhan_n · Accepted solution]

Instead of using DOES NOT EXIST (which is not logical as it is present in the Payload) try to check the value of the field with some dummy value, if the field exists then the value will be true if not false....

[Former Member · Accepted solution]

Hi Latika,

I dont have any other element which I can compare instead of NAME.

Hi Latika,

Some how I managed to get 2 fields and tried my scenario.

One more observation here is Interface determination condition editor

works fine if inbound interfaces are different. But it does not work if

inbound interfaces are same.

Any idea on this?

go with BPM only

[bhavesh_kantilal · Accepted solution]

Manually key in the XPATH and use the Not function.

not(node exists)

Exact syntax will be here,

Hi Bhavesh,

I tried by manually giving the condition in XPATH but still it is not working.

[Former Member · Accepted solution]

Thanks a lot. Problem got solved by adding not function in XPATH.

[bhavesh_kantilal · Accepted solution]

Gouri,

Would be helpful if you can give us the exact syntax that did the trick.

Thanks,

(/IDOC NAME[not(Field Name from IDOC which u want to compare)] EX ).

I am trying to get this sort of check on the LIFNR field of a CREMDM idoc. If you are still watching this thread, could you tell me what is wrong?

(/CREMDM04 not(/IDOC/E1LFA1M/LIFNR) EX )

Thanks!

Hi Guys,

Could you please give us the exact syntax ?

Thank you.

of course you can add condition in interface determination.

or how do you determinate inbound interface.

but after when you add multiple inbound interface, the screen apperar condition column between inbound interface column and interface mapping column!

you have to add 3 inbound interfaces to be appeared condition column.

Hi Gouri ,

You can do N:N mapping and you can apply logic such that if Field Name has some value then u will map your first structure and if it is empty u will map your second structure ,u can use If Else Function for that .

If still it is noty cleare just reply back to me

I dont want to do anything in mapping. Because my mapping programs are ready. Only in interface determination I need to put a condition which will decide at runtime which mapping program should be used.

I hope you are getting my point.

hi gouri,

I think you should use node Functions for this. CreateIf Node function.

I can use node functions in mapping. But before executing mapping I want to decide mapping program. which is possible with interface determination conditions. Any idea how to specify those conditions?

hi,

excuse me, i didnt get properly the last time.

Anyways conditional mapping is possible. Check this out

I have already mentioned that I have followed Help.Sap.com link.

If possible please help on how to specify conditions in Interface determination.
