Hello @Kamasanirajesh,
There is an option called VIF(Variance Inflation Factor) which you can use during Logistic Regression using SAS.
Values of more than 10 are indicative of the presence of multi-collinearity.

Hi Shuvayan

Thanks for the reply, I have added VIF function while runig logistic regression in SAS it is throwing an error.
Is there any other funtion to deal with Multi-collinearity in SAS Logistic regression.

While you wait for the answer specific to the error in SAS, you can try with Principal component analysis. This is also a technique used for identifying multicollinearity.
