After the upgrade of SAP BASIS [SAPKB70217], BBPCRM [SAPKU70114] and WEBCUIF [SAPK-70114INWEBCUIF] we are not able to open in WEB_UI any attachments by business partner, contact persons or any other CRM activities.
After we have set the User Parameter "WCF_IGNORE_ENHANCEMT = 'A' " everything worked fine. The attachments could be opened again. Searching through the SCN Wiki and Google we found out that the user parameter deactivates any customer ENHANCEMENTs.
Do you have any suggestion how to continue by the analysis, which views, CRM_UI Workbench Componentes relates to the Attachments?
Thank you very much,
Best Regards,
Zoltan Varga
