We have created a Z field using AET in WebUI which is already moved to Production system. This field has a Get and Set method customized to populate its value.
Now we have included similar field with a similar logic. The issue is that now the earlier field is not able to read certain attribute values using the standard method IF_BOL_BO_PROPERTY_ACCESS~GET_PROPERTY_AS_VALUE
Line......LV_PROPERTY_REF = GET_PROPERTY( IV_ATTR_NAME )
We have not made any changes in the code, then why the system is unable to read the attribute value in our Test client.
Cant answer your question without debugging but below are few things you can try out:
1. In case you are writing custom code, try to use other method like get_property_as_string or get_property and see if they return a value.
2. Check your design layer if both the fields are present there.
I don't see any other reason. If no luck with above two then please raise an OSS.
