Hi

Did you first get a reference to the node and create a new element for that node before you use the set methods?

If not use the following:

I<node name>Node myNode = wdContext.node<node name>();

I<node name>Element newEl = myNode.create<node name>Element();

where <node name> is the name of your context node and then you can say

newEl.setMatnr_Low("*" );

newEl.setOption("CP" );

newEl.setSign("I" );

myNode.addElement(newEl);
