In the table com_vtiger_workflowtask_queue I suppose are stored the information to be processed. The field entity_id contain the entity to be processed, for example in my case 5x1000 means:
5 = Modules Potential i.e. table vte_potential
1000 = the value of potentiaid of the vte_potenzial.
What are the other possible values? Where are stored?
