Posted on by Ramonjairo31

Hello everyone, I need some help from you

I’m trying to take the overall start date, input that into the start date of the first line and then add the number of days to get the end date and then use this end date as the start date for the next line and so on,

Post data: I have the repeating table working fine so far what I need is update Start date and end date on the lines as described above. I need to have this done in PowerApps, This Picture is only to be illustrated by it

Do you want to do this in Excel or Powerapps?
If in Powerapps, is it on a form

Assuming you have only one line (One record ) and you want a second line or row:
Insert a TextBox1 and in the Default put:
LookUp(Table1,Decription=TextBox1.Text,EndDate) ...This will pull the old end date

If you have a TextBox2 which will record EndDate for next line/record put:
DateAdd(DateValue(TextInput5_3.Text),5)

Hi @Ramonjairo31 ,

Do you want to create a screen like the screenshoot that you provided?

Do you want the startdate will be the last enddate automatically, the end date will be the startdate+days?

If so, I've made a similar test for your reference:
1)my data source:

listname: user_form1

fieldname: start date(date type), end date(date type), days( number type), task(text type)

2)my app:
insert these controls: 2 textinputs, 2 datepickers, a submit button, a data table

set datepicker1's DefaultDate:

If(IsEmpty(user_form1),Today(),Last(user_form1).enddate)

set datepicker2's DefaultDate:

DateAdd(DatePicker1.SelectedDate,Value(TextInput2.Text))

set datepicker2's DisplayMode:

Disabled

set submit button's OnSelect:

Patch(user_form1,Defaults(user_form1),{task:TextInput1.Text,days:Value(TextInput2.Text),'start date':DatePicker1.SelectedDate,'end date':DatePicker2.SelectedDate});Reset(TextInput1);Reset(TextInput2)

set the datatable's Items:

user_form1

Then the screen will just like what you description.

Do not forget to replace the fieldnames, listnames,control names with yours.

Best regards,

Hi @Ramonjairo31 ,

Yes, since every record's start date and end date has relationship, so if you modify one record, you also need to modify other records.

For example:

if you make task1 to task3's original time, you need these formulas:

Patch(user_form1,LookUp(user_form1,task="task2"), {'start date':LookUp(user_form1,task="task1",'start date'),//task1's start time 'end date':DateAdd(LookUp(user_form1,task="task1",'start date'),LookUp(user_form1,task="task2",days)) //task1's start time+days }); Patch(user_form1,LookUp(user_form1,task="task1"), {'start date':DateAdd(LookUp(user_form1,task="task3",'end date'),-LookUp(user_form1,task="task1",days)),//task3's end time+days 'end date':LookUp(user_form1,task="task3",'end date')});//task3's end time Patch(user_form1,LookUp(user_form1,task="task3"), {'start date':LookUp(user_form1,task="task2",'end date'),//task2's end time 'end date':LookUp(user_form1,task="task1",'start date'//task1's start time } ) //the order will become task2->task3->task1

Best regards,
