PowerApps – Merge Two Lists with Same Column Name

By Vinod Thachin -

While merging two SharePoint lists in Power Apps, I have used Employee ID as a lookup Column. But both lists are using Same Name as “Employee ID”.  

To Fix the issue, we need to use “With” function to update the column. Here are the logic I have used to merge the lists.


Here “NewStudAdmin” is a partial data. Here With function evaluates a formula for a single record. This formula calculate the value to perform actions to modify the data while working with collections.

The above formula will work to combine two lists data based on Employee ID.

Here EmployeeData1 – LIST1

EmployeeData2 – LIST2

We need to merge these two lists based on Employee ID common field in the two lists. When I try to merge these lists with ForAll and Lookup without “With” function, I got an error “Incompatible to comparing the two lists in the Lookup”

Hope this helps.

Linksys Wireless Connection Failure

By -
I configured the Linksys wireless router [WRT54G] couple of years before and it just worked great. I myself configured the password and everything worked great at my home. Anyone comes in home takes my password and it just worked great most of the time. all these were with windows server 2003 and Dell machaines. When I bought a new Hp DV9000 (XP) I had an issue connecting to the home wireless. I started browsing and found this solution: Issue : Couldn't connect to the selected connection. 1.

Power Apps toPower Automate Error - The input body for trigger 'manual' of type 'Request' did not match its schema definition , the input String does not validate against the date

By Vinod Thachin -
While working with power Apps to Power automate, passing the Date time values as Text(DateTimeValue) throws error as below. The input body for trigger 'manual' of type 'Request' did not match its schema definition. Error details: 'String '' does not validate against format 'date'.'. After checking the Microsoft documentation and few blogs i found out the date values should be passed as a formatted date time. TO pass the date time  we need to use following functions. Text(<<DateTimePicker>>.SelectedDate,"[$-en-US]yyyy-mm-dd") Even after passing the value i am still seeing the same issue and finally found out the default value ids sending as empty and formulae failing for empty values. So we need to make sure the Date Value should not go blank to the formulae and the value should be formatted using the formulae as above. Hope this helps.
