In the model operation, I did not see any function to add reference to the model element.

For example
model element A have a reference to model element B

I created element A using tool and used the model operation SET to set its featuere 'name' accordingly.
But what operation should i use to add the reference to B.

Any help much appreciated

Hello,

To display a reference on your diagram you will need an edge mapping
using the mapping you created to represent your model element A and B as
source/target. See Documentation "Sirius Specifier
Manual/Diagrams/Layers and Graphical Elements/Edges" for futher details
on Edge Mappings. You can also check into the tutorial part
https://wiki.eclipse.org/Sirius/Tutorials/4MinTutorial#Add_a_Relation_Based_Edge.
Then, to be able to add a reference from model element A to model
element B, you will need to add an "Edge Creation" tool referencing your
"Edge Mapping". See Documentation "Sirius Specifier
Manual/Diagrams/Layers and Graphical Elements/Edges/Edge Tools" for
futher details on Edge Mappings.

You can use a Set operation too, in the reference, you just enter the
name of the EReference in your meta-model. Then in the value expession,
you put an expression whose result is B, for example var:target, if you
are in a tool which defined a varable named target which is your B.
