Message type: E = Error
Message class:  S_CUS_IMG_ACTIVITY - IMG Activity 
Message number: 169
Message text: Field &2 of table/view &1 cannot be maintained in this table/view
You cannot maintain the field '&V2&' of the table/view &V1& in the BC
Set, in this table/view.
<ZH>Background:</>
The original table (&V3&) of the field '&V2&' in the table/view &V1& has
no foreign key relationship to the primary table of the table/view &V1&
which would let you change the field. Either the original table &V3& is
not in the object definition of the table/view &V1& (see piece list of
the table/view in the transaction SOBJ), or the DDIC flag is not set for
this table. You can only maintain such a field directly in the table
&V3& or in a view basd on it which has a foreign key relationship to the
table &V3&, but not in this table/view &V1&.
As you cannot maintain the field '&V2&' in the table/view &V1&, it is
automatically removed from the BC Set when it is displayed in change
mode in the BC Set maintenance transaction. The field was not excluded
by earlier versions of the BC Set maintenance transaction, so it must be
done now. The current version of the BC Set maintenance transaction
excludes such fields (you cannot select the field in the field
selection).
If you activate the existing BC Set unchanged, the contents of the field
'&V2&' are not activated, which would cause differences between the BC
Set and the customizing table.
Go to the BC Set maintenance transaction in change mode for the current
BC Set. All fields of this sort are automatically removed from the BC
Set. Save the BC Set.
<ZH>BC Set consistency</>:
No information is lost when you remove "Not Maintainable " fields from
the BC Set. It has always been necessary that the tables/views in which
these fields can be maintained are put in the BC Set, to be able to use
these fields correctly in BC Sets, for documentation or BC Set delivery
purposes.
The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
