Hi,

Create a new JCO(for both Meta Data,Model Data) connection in Content administrator>Webdynpro>Create JCO destination

and Make use of that Jco.Otherwise check the status of your Meta data.ModelData Jco connection in Content administrator>Webdynpro>Maintain Jco destination.

Hi

The backend to which to connect at Runtime is not the same as the backend from which you imported the model. This could cause inconsistencies. You need to run with the same backend from where you imported your model.

Hi,

Can u elaborate and tell how to make Bapis active

Hi,

In JCo Creation, you have to select Model data and Meta data for a pair.The Model Data is to get the actual data(i.e Records) and The Meta data is to get the Data about the Tables and Structures.So you have to use Both the Model and Meta data.

Hi Satish,

Do u mean that we have to select Modeldata RadioButton for WD_MODELDATA_DEST and metadata radiobutton WD_RFC_METADATA_DEST after clicking CREATE button on each of them

Hi padma,

Check Sap Note 991175.Its a bug .we got it for some other bapi.If u r using 7.0 patch 11,a hotfix is available for this.In the note everything is specified.

U can get this note at www.service.sap.com.In that u have to give the sap note no. & search for that.
