How To Fix ECN301 - Data environment is incomplete: too many objects

ECN301 - Overview

• Message type: E = Error

• Message class: ECN - Message class for IS-U navigator customizing

• Message number: 301

• Message text: Data environment is incomplete: too many objects

What causes this issue?

The data construct shown in the data environment display contains so
many objects, that a complete selection and display, as intended by the
navigator configuration, would take too long.
A maximum of &V1& objects are currently displayed.

System Response

The selection was suspended. However, only complete selection levels
have been excluded, meaning that the selection levels displayed contain
all their corresponding objects.
If a level contains over &V1& objects, the system does not continue to
select dependent objects for the corresponding object.

How to fix this error?

You can continue processing; however, the data environment displayed
does not contain all the levels intended by the configuration.
To display more information about the data environment, place the cursor
on the object for which you want to see additional dependent objects and
display the data environment for this object.
Alternatively, you can use the user parameter (set/get parameter ID)
ECN_MAXROWS in your user profile to change the maximum number of objects
displayed.

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
