PSS - Password Parameter

Hi ,

I currently configuring PSS for our old system which is a R/3 4.7 but when I tried to reset the password I am getting the following error message.

In back-end and GRC I already set the password to have one minimum special character.  Have also maintain GEN_PSW_MAX_SPECIALS in the table PRGN_CUST .

For ECC system I don’t encounter such problem .  

Is this due to the GRC support package or PSS with GRC10.1 would not work with 4.7 Environment . Checked the SAP Note 1666807 but since we have GRCPINW have V1000_620 level this can't be applied . 

Regards

Kumar
