URGENT:Error in Transaction HRUSER

Hi,

I have installed and configured ESS 1.0 WD version. Now when I go to ECC 6.0 to assign employees to the user ids through the transaction HRUSER. I get an error like error occured cannot assign employee 123456 to user ID ABCD.

I have also tried entering user id in PA30 infotype 105 subtyp 0001.Thereit gets saved but is not reflected in the EP ESS. The ESS R/3 however works.

I tried debugging HRUSER and found that the subtyp 001 is passed as 10. I corrected that in debugger so the employee got assigned.

I want to ask am I doing some step wrong or some configurations needs to be done before using HRUSER transaction.

or is it more like a bug?

All suggestions are welcome and will be rewarded accordingly.

regards

Justin
