Problem

--If you want to add a custom attribute in the DML simulation in order to test some maps without deploying to the B2Bi

Resolution

--You need to use B2Bi Client 2.6 UP2022-10

--Simulate the map, then go in Attributes tab, click on the plus button, chose one attribute, click on the name, add your custom attribute name and the value (see Custom_attribute.png)

--You can check this by adding a trace in the Main Block:

addTrace( "INFO","test: " + getAttribute("B2BXGIReceive_ConsumptionFilename")) (see addTrace.png and DataProcessingLog.png)
