I want to deploy a bdm with 350 attributes but it is allowing only 255 .
I managed to generate a bdm with an object with 350 attributes. The error you get is caused by a request having more than 255 parameters. It is not supported to have more than 255 parameters for a method in java.
I suggest updating your data model and split this big object into several objects and use aggregation or composition relation or remove the unique constraints on each attribute of your object if it is the case.
Indeed, this is not a good practice to have so many attributes in the same object.
Functionally, you can probably cut your business object into several objects with real business meaning. It will ease the understanding and the use of your business design.
thank you romain.bioteau
after creating how can i retrive that entire data to custom ui page.
thanks in advance.
