SAP S/4HANA Cloud Public Edition

1. Create a Service Purchase Order (Manage Purchase Orders) 
   
2. Create a Service Entry Sheet (Manage Service Entry Sheets - Lean Services) 
   
3. The Service Entry Sheet is marked for approval and sent to the inbox of the approving manager. 
4. The approving manager accesses 'My Inbox'. 
5. Approve the Service Entry Sheet, but it remains in the Inbox and Error appears.

Missing Authorisations

Approvers of 'Service Entry Sheets' - need a business role containing the authorization objects:

• M_MSEG_BWE (Activity = 01; Goods Movement Type = 101, 102)
• M_MSEG_WWE (Activity = 01; Plant = *)
• M_SES_EKG (Activity = 03, 37, 74; Purchasing Group = *)
• M_SES_EKO (Activity = 03, 37, 74; Purchasing Organization = *)
• M_SES_WRK (Activity = 03, 37, 74; Plant = *)

 The activity '*' or '37'(Accept).

So to overcome this issue,assign business role: SAP_BR_PROJ_MANAGE_COMM to your approving user or assign business catalog SAP_MM_BC_SES_WIAPPROVE_PC to an existing role of the user.
