sapui5 - How map authorizations (and other sub-infos) in oData structure -

this base schema of odata edm: thanks image filippo

i have db structure:

product (code, description, iva, price) |n | | | |1 purchase(id, product, customer) 

i want expose data using odata; can map in natural way product , purchase in 2 entityset: productset , purchaseset.

if require example items of productset receive collection of 100 products; each product have 4 properties, example:

{    code:01,     description: "blue pen",     iva: "19",     price: "2.99" } 

ok based on user logged, business logic before odata want send me more information (for example editable sub property):

{    code: {value:01, editable:false},     description: {value:"blue pen", editable:false},     iva: {value:19, editable:true},     price: {value:"2.99", editable:true} } 

(i can't sent new information in mode, have entity sets , properties...)

what right way map editable infos in edm? new property??

you can achieve creating complextype have properties of value , editable. properties of entity refer complextype.
