Case : XXXXXXX refers to an object that cannot be accessed

Hi Friends,

I am not able to save the case and getting below mentioned error message.

"Case : XXXXXX refers to an object that cannot be accessed"

When i click on the error message Details I am getting this

Diagnosis

Case contains a record instance referring to object (XXXXX) that cannot be accessed, either because it was deleted or it was archived.

Procedure

You must delete the record instance of this case before you can save.

In the Method : GET_CRM_CASE_REF

* Look for the CRM Case referene in the global table

  READ TABLE gt_crm_case_tab WITH TABLE KEY
        case_guid = iv_case_guid
        INTO ls_crm_case_ref.

  er_crm_case_ref = ls_crm_case_ref-crm_case_ref.

Here we are not getting the " er_crm_case_ref" field value

and an exception is raising.

Please guide me how to rectify this issue

Regards,

Ganesh
