Json serialize: empty structure with no fields

[former_member760202]

I need to create a json string, am trying to use /ui2/cl_json=>serialize. The thing is a part of json I need looks like this:

"forms": { }

So it is an empty structure with no fields, can it be created in abap?

CALL TRANSFORMATION allows to "supress initial components", but I think it can't help me, because in an other part of that json I need to save initial components, like: "data": { "password": " " }
