Function /DocumentIsValid not found in the metadata !

Dear Experts

When I call my function import in my SAPUI5 code, I receive the error message above (in subject). Please take the details from the descriptions below.

01. Implementing Function Import (SEGW)

02. The redefined method EXECUTE_ACTION

  METHOD /iwbep/if_mgw_appl_srv_runtime~execute_action.

    ENDCASE.
  ENDMETHOD.

03. Checking the metadata of OData Service

Code section with "function import":

04. Test call of function import in /IWFND/GW_CLIENT

Request URL:

/sap/opu/odata/sap/{SERVICE_NAME}/DocumentIsValid?DocArt='ZAA'&DocStat='SP'&$fo
rmat=json

05. Calling the function import in SAPUI5

…
this.oAppModel.callFunction("/DocumentIsValid", {
  method: "GET",
  success: fnSuccess,
  error: fnError,
      urlParameters: {
      "DocArt": sDokar,
      "DocStat": sDokst
  }
});
…

The full error message is:

Assertion failed: EventProvider sap.ui.model.odata.v2.ODataModel: Function /DocumentIsValid not found in the metadata !

06. Troubleshooting

The HTTP method GET, POST etc. are supported by the OData Model v2
Modification on the function import (SEGW) didn't bring the solution

Many thanks und best regards

Hey Cengiz,

Please, show US what is behind this.oAppModel.

Best,

Michal

check the metadata in your browser, did you see the function there?

michal.majer : Hi Michal. Thank you for your response. The code behind the "this.oAppModel" you can find under the subtitle "05. Calling the function import in SAPUI5". Is that what you mean?

a20200220 : Hi Jun. Thank you for your response. The XML code section "03. Checking the metadata of OData Service" is from the browser's metadata.

Maybe this is also an interesting code section behind the "this.oAppModel":

this.oOwnerComp = this.getOwnerComponent();
this.oAppModel = this.oOwnerComp.oAppModel;

Could You share also Component.js? It seems there could be problem with oAppModel.
Check if it's correct. Is it not undefined during function call?

Maybe You could try:

 this.oAppModel = this.oOwnerComponent.getModel()

Hi together

The issue is fixed. The problem was using the wrong "this" initiation.

WRONG:

var that = this;
....
this.oAppModel.callFunction("/DocumentIsValid", {
   ...
}

RIGHT:

var that = this;
....
that.oAppModel.callFunction("/DocumentIsValid", {
   ...
}
