it's one type of load, it's used replicates the data model of an existing qlikview app into another qlikview app without accessing the original data source, once the model reproduced into another qlikview document then u can try your chart objects. this method much faster than other base qlikview document.
remember below point while doing binary load,
1) this binary load statment should be in the first statement of a load script.
2) you can only perform one binary load per script/qvw (i.e u can't do nested binary load doc.)
3) it won't copy the chart objects of the base document.
let say one exampe,
your have A.qvw is the base document
you can create new document all call that existing document using below script
