How To Fix KR320 - Enter a cost object group or an object number set

KR320 - Overview

• Message type: E = Error

• Message class: KR - Archiving Reports and Utilities

• Message number: 320

• Message text: Enter a cost object group or an object number set

What causes this issue?

You want to archive line items for cost objects or you have not entered
an object type. To select the objects for which the line items are to
be archived you entered group &V1&. However, this group is neither a
cost object group nor a general object number set.

How to fix this error?

Check the following alternatives:
Have you entered the correct object type?
If you want to archive line items for cost objects, you must enter
"COB" as the object type. If you wantt to archive line items for
different object types (e.g. cost objects and cost centers) in one
session, you should not enter an object type.
Have you made a typing mistake?
A group with a similar name might exist that has a different reference
(e.g. a cost center group). Check that &V1& is reeally the required
group.
Do you want to process all cost objects?
In this case you should leave the "Group" field blank. If you do not
enter a group, all the line items for cost objects that meet the other
conditions will be archived. Other conditions could be, for example,
the chosen controlling area and the residence times.
Do want to process just certain cost objects?
Then you should choose a cost object group that contains those cost
objects. If necessary, you must create a suitable cost object group.
Do you want to archive line items for certain objects but for different
object types?
In this case you must create a general object number set (a set for
field CCSS-OBJNR). We do not, however, recommend this alternative.
