    Hi Abdelrahman

    I hope you are looking for the Post hoc test in non-parametric tests that performs multiple comparison between all combinations of groups. For this begin with Analyze -> Non-parametric test -> Legacy Dialogs -> K independent samples, choose the Test field and Grouping Variable, define range and select Krystal Wallis H test, click OK. As the Kruskal Wallis test calculates the significant difference between all groups and does not identify which two groups are significantly different and which of them are not, again proceed with Analyze -> Non-parametric test  -> independent samples, choose the variables under Fields and Group, then click Settings and select Customise Test, here you can see the option of Kruskal Walis test with multiple comparisons. Run this and view the output . If required, double click the Output so as to analyse various options.

    Regards
