When we use punch out catalog we get login error after upgrade to srm7

Hi All,

Good Day!

We have upgraded from SRM 5 to SRM 7 Ehp2.

Issue Here is; Two of the Punchout Catalogues are not working after upgrade.

In one of the punch out catalog; We could not able to login and getting the login error when we log in due to special characters in hook-url. We did not have this issue before the System upgrade.

In another Punchout Catalogue; we are able to log in but not able to be returnback to the srm application and getting the "http 404 error" . 

Please provide your valuable inputs and help us for closing this.

Thanks & Regards,

Kalappa.
