Ignoring type value as it is not in the attribute set

[MunirajM]

Hi,

I am trying to use Magmi for my M2.4.x store. I have created a new multiselect attribute with attribute code as "benefits" but I haven't created any options for this attribute. Also, I have assigned this attribute to the attribute set with id 8.

Then I have created a csv file with 2 columns as below,

"sku","benefits"
"ABCDE","FGHIJL"
"MNOPQ","RSTUVW"

Expected Result:
Creating the new attribute options under the "benefits" attribute if these options are not already available from csv.

Actual Result:
When I try to import this csv file, I am getting the error as "Ignoring type value as it is not in the attribute set 8" but on the fly custom attributes creation is not working.

Notes
I am trying to update these options for the already existing products.

Please let me know if I am missing any setting on Magmi.

Thanks
