Part Revision remains "Not In Effect" despite past Phase In date

Hi all,

I have an issue with a part revision in IFS Cloud.

• There is only 1 part revision
• The Phase In date is 01-01-2025 (in the past)
• The product structure has the status buildable
• The status still remains “Not In Effect”

When releasing a shop order, I also receive the warning:

“The default structure revision [1] for shop order [...] is not effective on the start date 20-05-2026 16:03. Do you want to continue?”

Questions:

• Why does the revision not automatically switch to “In Effect”?
• What conditions could block this, even when there is only one revision and the Phase In date is in the past?

Thanks in advance!
Kind regards, Willem
