Can't display any BSP pages after upgrade.

Hi

We have implemented the latest SP and patches on our SRM 4.0 system, running on 6.40.

After the upgrade we can't display BSP pages any more. We get the same error message on them all:

<b>A string reference with destroyed context was destroyed</b>

If I go in ST22 we displays the error message: STRING_BAD_REF

What happened?

Error in ABAP application program.

The current ABAP program "CL_BSP_MODEL==================CP" had to be

terminated because one of the

statements could not be executed.

This is probably due to an error in the ABAP program.

Have anyone experience anaything like this?

Help is appreciated

Best Regards

Morten
