SAC Table Calculated measure - Column Adding comments

Hi,

I have a requirement to add a column with texts. It should be entered by end user as a comment.

In story table view, I have 2 columns as Product and Comments.

For Ex.

Product Comments

P001 Missing Parameters

P002 Covid-19

P008 Value is not correct.

I don't want to use story level comments or page comments. (Similar to in BW-IP Characteristics as a key figure)

Is it possible to use it in measure based model.

Regards,

Sheeba
