Hi ,

can any help me to solve the problem

Hi Raj,

Can You have a look at yr code containing the problem I have mentioned regarding the return.

Also first chk the RFC manually with the value and see whether it is working fine or not.

Also when U will execute the RFC the response will be an XML string and You will have to extract the required field from the Response XML and put this extracted field in yr return

esle thee node will contain the xml returned from Lookup

Regards

Hi Raj,

As u have mentioned that RFC is working fine then U must be getting the response back in the Lookup as XML .

So please tell me what is the problem Do u want to extract the value and facing problem there ?:

Please check the below blogs.

Lookup method from GUI mapping can be called using any of the following ways.

· RFC lookup using JCO (without communication channel)

· RFC lookup with communication channel.

Hi,

Can u confirm if dis value is present inside the table which u r sending to target by executing ur BAPI first.

Hi Anoop,

I sending the Value from Soucre.

I need to check the value exist in R/3 if its exist then send to Target.

Lookup will do only checking . I am confused to write a java Code.

yes i agree i am returing Null .

Hi,

U r sending value from the source.This value will be an input to ur UDF which is doing RFC lookup corresponding to that value.For that u must have written code in SE37.just confirm if u r giving the same value as from the source to ur function module,does it return something while executing?

Hi Raj,

Please check the code you are returning null strign in the return statement .Please correct the return content and then check the same.
