IC Context Area ToolBar buttons disappear when using Internet Explorer and Edge


we are facing the problem that IC Context Area ToolBar buttons (call controls) in WebClient UI disappear from time to time without any clear reason and reload of the page is needed.

The problem occurs only when using Internet Explorer and Edge of all versions. In Chrome everything is OK, call controls are always visible.

We implemented Note 2539608, but the problem did not disappear.

Maybe someone had faced this problem and managed to fix it? Any help would be appreciated.

    Hello Justas,

    What's your CRM versions ? What's the IE version?

    Maybe you can check if SAP Note 1682845 is implemented in your system.

    If this note is not implemented yet, please implement it. After the note implementation, clear both browser and server cache before you retest:

    Delete the server cache, please go to transaction SMICM -> GoTo
    ->HTTPPlug-In->Server Cache -> Invalidate Globally: "Yes" to invalidate

    Delete the IE cache, go to menu 'tools'->'internet options'->'general' tab , 'delete' button

    Best regards, Corrine

    • HI,

      It seems the 'session not found error' is a good point we should check.

      1. This is important -- are you using web dispatcher or something regarding load balance? If yes, does the problem happen only when the web dispatcher(or load balance) is being used? Or it also happens without using them?
      2. And also, please check in your httpwatch trace: Normally, ESID is being used in CRM WebUI and IC. for example, in a request url, you will see ..../sap(ZT1Lak96bjJQYmExZVoyaV9uRjB1UUpnPT0taFktZEtqa0h0ZTUxaVZTTld0RWF3PT0=)/bc/bsp... .
        And also, you can find parameter 'ESID' in 'POST Data' part, its value will be like (ZT1Lak96bjJQYmExZVoyaV9uRjB1UUpnPT0taFktZEtqa0h0ZTUxaVZTTld0RWF3PT0=). Please check if the requests (which has error 'session not found') contain different ESID values?
      3. Please goto SPRO-> Customer Relationship Management-> UI Framework-> UI Framework Definition-> Additional Settings for UI Framework-> Define External Session ID. Is there any entry maintained there? What are they?

      Best Regards, Corrine

    As mentioned by Corrine, the root cause of your issue might be related to session problems. There are two main issues which can cause that the request cannot enter the right session -

    • sessions are not routed to the right application server (where the application session is hosted) due to load balanching problems
    • sessions timed out in the meantime at the backend and are therefore not available anymore
