• Message text: Call with external call number &1 could not be modified

What causes this issue?

The reason for this might be that no parts groups/components have been
defined or transferred for this JIT call. It is possible that the
internal keys of existing JIT calls/parts groups are not tranferred.

System Response

The system does not modify the JIT call.

How to fix this error?

First, try to save the JIT call again.
Check whether the appropriate data was transferred correctly. If the
JIT call is to be modified, the appropriate parts groups/call
components must be transferred.
If you are creating JIT calls or parts groups, you must transfer one
JIT call only!
If none of these reasons apply, there must be an internal error. In
this case, please contact your system administrator.
