Message type: E = Error
Message class:  CNV_00001 - Message class for CWB settings maintenance programs 
Message number: 230
Message text: Package &1 cannot be used as source package for field &3 of table &2.
Package &V1& cannot be used as source package for field &V3& of table
&V2&. This can have 2 different reasons:
Package &V1& does not belong to dependencies of the current conversion
package (it was not blended during the package load procedure)
Package &V1& does not define any conversion-relevant data types (in
table CNVDOMS). Only packages defining such data types (domains or data
elements) can be used as source packages.
If the correct source package is not provided the field &V3& of table
&V2& may be converted incorrectly.
Provide a correct source package. Check input help (F4) for available
source packages. If you choose a conversion routine for this field from
amongst routines provided by SAP the source package should be assigned
automatically and should not be changed.
The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
