Distribution is locked due to BOM status

What causes this issue?

The BOM that is indicated by the |@06@ icon does meet your selection
criteria, but it has a BOM status that does not allow ALE distribution.
You can use the BOM status to set whether or not a BOM can be
distributed via ALE.

System Response

The system locks the BOM for post selection and ignores it during
distribution. The BOM is not distributed via ALE.

How to fix this error?

If you want to distribute this BOM, first select a status in the BOM
header that allows ALE distribution.
If you want to ignore the distribution lock for all BOMs, set the
<LS>Ignore distribution lock</> indicator on the initial screen.
