SAP PO, how to pass multiple values in URL

[former_member331912]

Hello everyone,

I am using PO 7.5 and developing a REST to RFC scenario. I am exposing BAPI_GOODSMVT_GETDETAIL, which takes 2 inputs. This means, URL will be of the form http://<server>:<port>/RESTAdapter/...?MaterialDocument=<value>&MaterialDocYear=<value>.

In sender channel, I have made this:

My Message Type is

So in UDF, I need to pass two inputs? Can someone guide me for that. I havent found any solution over the internet yet.

Without UDF and simple mapping, I get this error

"Cannot create target element /ns1:BAPI_GOODSMVT_GETDETAIL/MATDOCUMENTYEAR. Values missing in queue context. Target XSD requires a value for this element, but the target-field mapping does not create one. Check whether the XML instance is valid for the source XSD, and whether the target-field mapping fulfils the requirement of the target XSD: Runtime Exception when executing application mapping program com/sap/xi/tf/_MM_REQ_BAPIGOODSMOVEMENTDETAIL"

Looking forward towards response.

Thanks

Hi,

I resolved the issue by creating 2 separate UDF's. Not sure if its an effecient solution.

Thanks.

Hi Iqbal,

Could you please share the URL pattern and the code you wrote to get two different values in payload.

Hi,

Please suggest how did you fix multiple values issue.

On another note, if I need to pass 3 parameters like

http://<server>:<port>/RESTAdapter/...?MaterialDocument=<value>&MaterialDocYear=<value>&Var=<Value>, how will I get 3 variables in UDF? And in channel configuration.

Hi!

The most straight-forward way, I see (and which is described in mentioned blog), is to create UDF with two input parameters (one - for DC attribute name and the other - for attribute namespace). After that you'll be able to use the same UDF for mapping different DC attributes to target fields.

Hi,

Please suggest on how to do the same to pick multiple values from URL .

e.g.

https://host:port/RESTAdapter/<Endpoint>/<Input_Parameter1>/<Input_Parameter2>/<Input_Parameter3>/<I...;

Hi!

You might refer to this blog (or even others from the series) for better understanding:

Thank you for commenting.

This is an example for 1 input value, and I am using these as UDF in other cases where I have only 1 input.

My question is how will I cater for 2 values?
