Hi, I am afraid if you have any error in data file. It may be missing values, different names or invalid name of any factor or indicator in your file. Once have a look data file to correct prior to upload.

Thank you very much for your constructive information!

Dear Anwar Shah, there is a large number of missing value in my spss file and that is as a result of filtered items in my questionnaire. In other words, when a question is filtered for a respondent, that question appears as missing value in spss data view for that respondent. But do you know how can I deal with that?

Dear Poorya,

In order to deal with the missing data in Smart-PLS, you have to define it first in order to handle it properly in this software. As I see from the previous comment you already have the SAV file, please save the dataset as a CSV, then open it with excel and try to change all the missing fields with a specific number (change all empty spaces to 999 for example). Your data is now ready to be imported in Smart-PLS but you have to put (999) in missing value maker field that will appear once you imported the data.

All the best

Dear Ahmed, I very much appreciate your kind reply. I just succeeded to import my data set in PLS. But, still there is one issue to deal with. when I want to do the PLS Algorithm, I have to choose one from three different options in missing value field. Actually all the missing values in my data set are as a result of filtered questions that I have in my questionnaire. I mean that when a question is filtered for a respondent, that question apprears as missing value for that particular respondent. Therefore, I'm thinking that which option (Mean replacement, caseweis deletion or Pairwise deletion) shall I finally choose.

Hi I import data, there are indicators but when i click the import button there is nothing on the screen? There is no missing value or error. Does anybody know why?
