Key does not correspond to mask: &

What causes this issue?

The key that you entered for the project definition or the WBS element
does not have the same length as was defined in the coding for one
section. The project coding determines the rule which governs how a
project number or WBS element key is set up.


Example
In Customizing for project coding, the following mask has been defined
for projects that begin with A: /00-XXX-000.
From the number A45ABC555 the system edits the number to create:
A/45-ABC-555.
In this case the system will <ZH>not</> accept the following entries
for the project number:
A45ABCXYZ
A4567ABC555

System Response

INCLUDE 'NA_ALLG_NOVERARBEITUNG' OBJECT DOKU ID TX

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Enter the key in its proper form: &V1&.
Use 0 for numerical characters and X for alphanumerical characters.
Enter the project identifier <ZH>without separating characters</> (for
example, AA45ABC555 statt A/45-ABC-555)
INCLUDE 'NA_ALLG_VORGEHEN' OBJECT DOKU ID TX
Check that the coding for the project definition was entered properly.
Make any necessary changes.
