Property of Data Object has no type assigned

[former_member187990]

Hi All,

We are facing Property of Data Object has no type assigned on extension of a project.

Followed the blog http://scn.sap.com/community/gateway/blog/2014/08/08/extending-a-service-using-the-gateway-service-b... and extended the project. After genertaing the extended project and calling the parent service url error "Property of Data Object has no type assigned" thrown.

Entity type in the parent project/service does not have DDIC Structure reference and in the extended project new field added. Same works if i use ABAP structure reference.

Parent project is with Namespace and extended project is with Z name. Please suggest how to solve the issue and also how to extend projects created in customer namespace

Regards,

Satish

There were many replies earlier to different thread regarding this.

1. In Model Provider Class Ext - Redefine DEFINE method.
2. Then call

super->define( ).
model->get_entity_type('<Entity_Name>')->get_property('<Prperty_Name>')->set_internal_type(cl_abap_typedescr=>typekind_string ).
