After performing a partial compile, you may receive the following error from prescripts invoking DPR_GetAdHocData during job generation in a frontend or during job execution:
 Error during execution of 'OnGenerate' in logic module 'VI.DB.Entities.EventsEntityLogic'.
 Error generating processes for event Update.
 Error executing script 'Event_Update'.
 Error generation process step event UPDATE.
 Error generating process ADS_ADSGroup_Update.
 Error executing prescript.
[DynScripts.ProductScripts_XNqn2VBgcbTG4lNzDrYjxKMs250+AdHocDataException] Connection information for <Key><T>ADSDomain</T><P>a6234b87-778e-421a-a6d9-21b32820ca17</P></Key> could not be detected.
This is a product defect (29847).
If the error occurs, you can restart the affected frontend or jobservice. In the latter case you also have to reactivate the job.
You can also prevent the error from happening altogether by always performing a full compile instead of a partial compile.
Development has fixed bug 29847 in version 8.1. For technical reasons, the fix is not available for earlier versions.
