Error when creating stored process from custom task

[ShenQicheng]

Hi,

I created a custom task whitch output data to a table in a library with LibraryName = MY_LIBRARY and LibRef = MY_LIB.

After I add the custom task to EG process flow, an error occurs when I try to 'Create Stored Process' either through task's right click menu or process flow's right click menu.

The error says, 'The library MY_LIB can not be found.'

In my task I implement the override methods OutputDataDescriptorList just like the 'Calculate Running Totals' sample code does.

(Using SAS.Shared.AddIns.SASTaskDataDescriptor.CreateLibrefDataDescriptor to create a Descriptor and add it to the return list.)

And if I set the same output to the built-in Rank task, no error occurs.

And if the library name is equal to libref, no error occurs.

Any idea about this error?

The stored process execute in another session, it's probably why it doesn't find your libref, so you have to code the libname in your stored process

To expand: the library definition should have the information to identify the server as well as the path.

Thanks,

I understand that stored process run in another session but this error occured before the 'Create new stored process' wizard showing up.

With the same output data the built-in Rank task can be created from to a stored process successfully.

I guess the reason is the implementation of OutputDataDescriptorList, but I have no idea how to fix the problem.

Please help me.

I understand stored process run in another session, but the error occured during 'Create Stored Process', not running the stored process.

And the built-in task with the same output data can be created from to a stored process successfully.

The error can be reprodued by using the 'Calculate Running Totals' sample without making any change to it.
