As the attachment image shows, Is there any way that I can show the latest update time inside one card.
Anywhere will be ok. Also I want to show it on the page level.
If you have that Batch Last Run as a date field in your card...set it up as a Beast Mode "Called BM - last run"...then use Max(batch_last_run) -- which will give you the lastest date...and then create a summary number in your card with that value.
Thank you @NewsomSolutions
with your hint, I search such kind same issue solution.
I don't know why just use MAX('last_run_'), you can not find the column from summary fields.
I need to use concat('some string', MAX('last_run_')), then I can find the column from summary fields.
My solution is as below:
CONCAT('LAST RUN: ', DATE_FORMAT(MAX(DATE_SUB(`_BATCH_LAST_RUN_`, INTERVAL -9 hour)), '%Y-%m-%d %k:%i:%s'))
