critical problem with background task

[faq@saportal.net]

Hello *,

we encouter a critical issue, which is going to drive me to insanity: We have a background method, which works fine, if I test it out of the business object builder. However, as soon as this method is called from a standard task and/or a workflow, it runs into an error with the messages:

- Work item 000003765344: Object ZXXX method PROCESSBACKGROUND cannot be executed

- Object with runtime number '0' not defined

I double checked the binding between tasks/workflow and task/method a million time now. Nothing apprears to be wrong.

Please let me know, what the cause of this problem might be, since I have absolutly no clue why this master piece of german engineering (aka SAP) is complaining.

Looking forward for enlightenment...

Cheers,
Tom
