[SAPUI5] Add custom header parameter to all oData queries

Simply go to your Component.js file and add this line to the init function:

this.getModel().setHeaders({"myCustomParameter": "test"})

In a CAP Backend, you get this parameter from the express req object, which can be accessed via the req.http property:

req.http.req.headers['myCustomParameter']

And here is a nice code snippet, on how to read this header parameter in an ABAP system: https://answers.sap.com/answers/425621/view.html

[SAPUI5] Suppress default oData error message / display meaningful error messages

Create a separate ErrorHandler.js file, like it is described here and either do your own error handler implementation, or take the sample from here. To avoid displaying multiple errors at once, follow this chapter.

Thanks to the provided dsag sample, this is takes only a few minutes and improves the user experience a lot!

[ABAP] xsdbool

Somehow I always forget that there is a boolean function in ABAP. That’s why I’m writing this post to hopefully remember it better. 🙂

If you just want to check something for truthiness, you can do it in the following three ways:

IF sy-subrc = 0.
  result = abap_true.
ELSE.
  result = abap_false.
ENDIF.
result = SWITCH #( sy-subrc WHEN 0 THEN abap_true
                                   ELSE abap_false ).
result = xsdbool( sy-subrc = 0 )

[CAP] Select max with group by

https://answers.sap.com/questions/13081527/simple-count-aggregation-on-caps-cql.html?childToView=13079907&answerPublished=true

entity myEntity {
        key ID: Integer;
        key seqNr: Integer;
        key createdAt: DateTime;
        ...
    }

@readonly
entity myEntityMaxSeqNr 
        as select from myEntity {
            ID, 
            count(seqNr) as maxSeqNr: Integer
            createdAt,
            ...
            } 
        group by 
            ID,
            createdAt;

This can also be done using CQL like here.

[SAPUI5] Create date object in UTC YYYY-MM-ddTHH:mm:ss

https://sapui5.hana.ondemand.com/#/api/sap.ui.core.format.DateFormat%23methods/format

            const today = new Date()
            const oDateTimeFormat = sap.ui.core.format.DateFormat.getDateTimeInstance({
                pattern: "yyyy-MM-ddTHH:mm:ss",
                UTC: true
            })
            const todayISO = oDateTimeFormat.format(today)

The UTC flag can also be set, when calling the format function.

            const today = new Date()
            const oDateTimeFormat = sap.ui.core.format.DateFormat.getDateTimeInstance({
                pattern: "yyyy-MM-ddTHH:mm:ss",
                //UTC: true
            })
            const todayISO = oDateTimeFormat.format(today, true)

[SAPUI5] Adding Lanes to a Process Flow

Manually adding Lanes to a Process Flow Control:

https://sapui5.hana.ondemand.com/#/api/sap.suite.ui.commons.ProcessFlow
https://sapui5.hana.ondemand.com/#/api/sap.suite.ui.commons.ProcessFlowLaneHeader
https://sapui5.hana.ondemand.com/#/entity/sap.suite.ui.commons.ProcessFlow/sample/sap.suite.ui.commons.sample.ProcessFlowUpdateLanes/code

In my case, there was no way to bind the model to the view, so I did the mapping for each ProcessFlowLaneHeader in the callback function after reading the oData entity.

view.xml

<flow:ProcessFlow id="process-flow"/>

controller.js

var oProcessFlow = this.getView().byId("process-flow")

var oRequestFilter = new sap.ui.model.Filter({
    path: "myId",
    operator: sap.ui.model.FilterOperator.EQ,
    value1: myId
})

this.getView().getModel().read("/WorkflowSet", {
    filters: [oFormularIdFilter],
    success: (oData, response) => {
        for (var i = 0; i < oData.results.length; i++) {
            var oLaneHeader = new ProcessFlowLaneHeader({
                laneId: oData.results[i].LaneId,
                iconSrc: oData.results[i].IconSrc,
                text: oData.results[i].Text,
                position: oData.results[i].Position,
                state: [{state: oData.results[i].State, value: "100"}]
            });
            oProcessFlow.addLane(oLaneHeader)
        }
    },
    error: oError => {
        sap.m.MessageToast.show("An error occured while reading entity /WorkflowSet.")
    }
});

[SuccessFactors] Process Trigger

In a Process Trigger, you can get a good overview of an employee who moved from REC, via ONB to EC.
