Export to excel outputs repeated information.

Posted on by nchandran 426

Hi i have two galleries, Main gallery A & nested sub gallery B. The idea is to export the information into CSV so i proceeded to create a collection to gather the gallery information shown below and export it to csv. It worked but im getting a repeated information in the csv table. Collection name is CsesAll. i set a code on the navigate button as below

ForAll(GalleyA.AllItems,Collect(CsesAll,{SAPID:Label21.Text,RequestorName:Label3_15,Vendor:Label23.Text,DateStart:Label8_30.Text,DateEnd:Label8_31,TotalFees:Label8_21,CostCentre:Label24,Evalcomplete:Label17.Text}));Navigate(ExportScreen)

 

THis navigates to the export screen and here Export button runs the flow -> ForAll(GalleyA.AllItems,Collect(CsesAll,{SAPID:Label21.Text,RequestorName:Label3_15,Vendor:Label23.Text,DateStart:Label8_30.Text,DateEnd:Label8_31,TotalFees:Label8_21,CostCentre:Label24,Evalcomplete:Label17.Text}));Set(varcsv,Concat(CsesAll,SAPID & "," & RequestorName & "," & Vendor & "," & DateStart & "," & DateEnd & "," & TotalFees & "," & CostCentre & "," & Evalcomplete& Char(10)));ExportCseAll.Run(varcsv,"External Training Records" & Now()).

Good news export works but I dont get the headers and the information is repeated in the same exported csv.

    Hi @nchandran ,

    You will see the headers I have added - also you need to refer to the gallery rows as below - I have also got rid of a Variable and Collection "hanging around"

    With(
 {
 wGal:
 ForAll(
 GalleyA.AllItems As aGal,
 {
 SAPID: aGal.Label21.Text,
 RequestorName: aGal.Label3_15,
 Vendor: aGal.Label23.Text,
 DateStart: aGal.Label8_30.Text,
 DateEnd: aGal.Label8_31,
 TotalFees: aGal.Label8_21,
 CostCentre: aGal.Label24,
 Evalcomplete: aGal.Label17.Text
 }
 )
 },
 With(
 {
 wCSV:
 "SAPID,RequestorName,Vendor,DateStart,DateEnd,TotalFees,CostCentre,Evalcomplete" & Char(10) & 
 Concat(
 wGal,
 SAPID & "," & RequestorName & "," & Vendor & "," & DateStart & "," & 
 DateEnd & "," & TotalFees & "," & CostCentre & "," & Evalcomplete & Char(10)
 )
 },
 ExportCseAll.Run(
 wCSV,
 "External Training Records" & Now()
 )
 )
)

    I think there was a missing ':' after wCSV fixed it. its not able to pick the label from the nested gallery b how can we fix it. After removing the nested gallery b label it worked but it only imported gallery A data. I need the subgallery colum which is Evalcomplete.

    Hi @nchandran ,

    Typo fixed (dangers of free-typing code).

    Which Labels are in the nested gallery ? Also what is the relationship between the nested gallery and the main gallery record it sits in ? Your problem here is a one-to-many relationship with the main gallery, so you can only (at best) pick up the first (or last) item from the nested item.

    Hi @WarrenBelz ,

    Typo fixed (dangers of free-typing code). -sign of a genius😃

    Which Labels are in the nested gallery ? only one for now which is  Evalcomplete: Label17 shows the evaluation status from the secondary source feeding the nested sub gallery.

    Also what is the relationship between the nested gallery and the main gallery record it sits in ? 

    Main gallery is for registered courses, nested sub gallery shows evaluation done for thoses course .

    In addition nested gallery source got a column called master ID which populates the same number as the ID from main gallery this allows me to retreive the related data. Items on nested gallery its like Filter(HRExtEval,MasterID =ThisItem.ID)

    Your problem here is a one-to-many relationship with the main gallery, so you can only (at best) pick up the first (or last) item from the nested item. : Thats the reason initially i did a collection of both galleries but found it too complicated and it was delivering the same repeated table.

    Hi @nchandran ,

    You would have been better defaulting the same formula in a Text control or Lable in the gallery if only a single value is returned, but try this (I have assumed the field name here)

    With(
 {
 wGal:
 ForAll(
 GalleyA.AllItems As aGal,
 {
 SAPID: aGal.Label21.Text,
 RequestorName: aGal.Label3_15,
 Vendor: aGal.Label23.Text,
 DateStart: aGal.Label8_30.Text,
 DateEnd: aGal.Label8_31,
 TotalFees: aGal.Label8_21,
 CostCentre: aGal.Label24,
 Evalcomplete: 
 LookUp(
 HRExtEval,
 MasterID = aGal.ID
 ).'Evaluation Status'
 }
 )
 },
 With(
 {
 wCSV:
 "SAPID,RequestorName,Vendor,DateStart,DateEnd,TotalFees,CostCentre,Evalcomplete" & Char(10) & 
 Concat(
 wGal,
 SAPID & "," & RequestorName & "," & Vendor & "," & DateStart & "," & 
 DateEnd & "," & TotalFees & "," & CostCentre & "," & Evalcomplete & Char(10)
 )
 },
 ExportCseAll.Run(
 wCSV,
 "External Training Records" & Now()
 )
 )
)

    @WarrenBelz ,

    Completely forgot about the lookup function, something new from this topic. Can i confirm what you did, you actually took one variable to capture the gallery columns into headers and another variable to output into the flow..correct me if I'm wrong here.

    Hi @nchandran ,

    Yes - also the With() statement can be nested or chained (as in this example) and saves Collections or Variable hanging around slowing your app. I have a blog on the subject if it is useful to you.
