Hi SAP Experts,
We are encountering an error with the Fiori application "Approve Purchase Requisition" when we attempt to approve/reject/forward the work order using the Fiori app.
The error thrown in the browser is an HTTP 400 error.
In the gateway log, the following error is present.
..ERROR_INFO RFC call was not successful because of system failure 'Function module "/IWWRK/WF_TGW_TASK_SCN_COUNT" not found.'.
The Fiori App is retrieving the data from the backend as we can see the data in the form. This error only happens when we try to approve/reject/forward the information.
From the GW client, all check OK, including the TASKPROCESSING service.
We have a Central Hub as our Gateway system (NW 7.40) and the SAP_GWFND process is at SP05. I have the gateway hooked up to a backend ECC system (EHP4/NW 7.01) for the backend components and backend SRM system for Cart Approvals (EHP2 for SAP SRM 7.0).
I have double checked that the following notes have been applied
1866093 - Patches for the Gateway SPS06 required for FIORI -> Running NW 7.40 Gateway Hub. SAP_GWFND is at SP05.
1799722 IW_BEP Adjustments to Task Gateway for SP06 - Geneva -> We are at IW_BEP SP07 which is above the requirement.
1805831 Workflow Support Decision options Nature -> Applicable for SAP_GWFND SP03. We are running SP05
1799807 Suppress Message /IWBEP/CM_MGW_RT 157 -> Cannot be implemented
1821503 Fixes to Task Gateway service - Consumer Scenario collection -> Cannot be implemented
1850312 Adding the Scenario collection to the TaskProcessing service - Cannot be implemented.
Has anybody ran into this issue or knows of a fix?
When clicking the approve action in the Fiori app, is there a better way to trace what is causing the failure besides the NW Gateway log and ICM trace file? The error in the ICM file is below. Increasing the ICM trace doesn't provide any further error details that what is listed below.
*** ERROR => Error in HTTP Request: Invalid header field(11) {00030017} [http_plg.c 5814]
Thanks in advance for any input!
