====== Generate transaction data and accompanying article catalog ======

A regular processing job (e.g. generate EDIFACT DESADV from FlatFile delivery bill) is used as trigger.

The article selection process is preferably done via [[prozessdefinition:jobs:jobsteps:allgemein:eventrouter|]] and [[prozessdefinition:jobs:jobsteps:allgemein:eventroutereceiver|]] outside the regular message processing.\ 
The [[prozessdefinition:jobs:jobsteps:allgemein:eventrouter|]] is then docked in the triggering job behind the transformer to eBiss MiddleWare located there.
With the [[prozessdefinition:jobs:jobsteps:supplier:tradeitemselectordirectsql|]] the positions contained by the previously created MiddleWare documents with //EANs// are provided to it for selection. 
Based on the EANs, the item detail information is now selected from the eBiss item master and converted from the source type **SupplierArticleDoc** to the target type **TradeItemDoc** using mapping.

If no price list is stored at trading partner, the default prices of the supplier article pool will be used.
