Ticket #1067892: The datastructure Salesorder were adjusted with Assignments specific columns. Several keywords were created and the corresponding fields are referencing on them. In regard to the choosen ordertype some fields were put to editable instead of invisible and some of them are mandatory as well. An additional action button is created in companies that leads to a assignment task. The quick entry was not able to implement due to the fact that salesoder and assignment are currently sharing one context and parameter transfer is not possible. Product owner said that this might be a feature for the future due to the fact that assignemt might will get an additional context.
