• Message number: 229

• Message text: Source package not defined for field &1 of table &2.

What causes this issue?

Source package not defined for field &V1& of table &V2&. This can happen
if more conversion packages are blended together and more than one
package wants to convert the field &V1&. The problem can also occur for
manually added conversion-relevant fields if the current conversion
package was created from more than one source package.

System Response

The lack of source package definition may lead to unsuccessful relevance
check during the conversion which usually causes the wrong data to be
converted.

How to fix this error?

Provide the source package for conversion-relevant field &V1& of table
&V2&
If you choose a conversion routine that belongs to a given source
package then the source package will be filled automatically. If there
is only one source package available it will also be updated
automatically. The source package should only be specified explicitly if
a custom conversion routine is provided.
