Not able to log the value of the lookup field

can  you post a screenshot how do you do that?

are you sure a value is populated in a list field?

what are the circumstanes when you want to get value written to log?

Hi emha,

Below are the screens of the original list, look up list and workflow and log history

was the lookup field already populated before you started workflow? or did you populate it withi workflow?

or do you change it's value within the workflow?

is "Document status" field your custom field or have you reused some OOTB provided one? 

I wonder whether the name is not reserved for some internal use and whether that doesn't cause problems. can you maybe try with a different name (create new field)?

I triggered the workflow once the item is created.

It is a custom field.

I already tried it by creating a new field with a different name but no result that way also

so, is it so that when item is created the field is empty, then you do some logic and set the field to 'Approved' and tries to log its value right away?

if it is so, then that would explain it - the value is not yet effectivelly to the list, so you can't see it.
