Help for Calculated/Conditional/Custom Column

Hi @tamerj1 @amitchandak @SpartaBI@Jihwan_Kim 

Could you please help me in achieving this either in DAX or PowerQuery.
One of my column in table has values like this.

raghukumarch_0-1660668552655.png

 

I wanted to create another column in same table by adding "0" in the begining for the values which dose not contain "-" and other value which contains "-" should remains same as it is. 

For example column 'C_SerialNumber' have values like "311211025073516" and "916429-19-11"

I wanted to add '0' in the begining if the value DOES NOT Contain '-'. So the output will be "0311211025073516" and other values remains same.

 

Thanks

Dear @raghukumarch ,

I have implemented your scenario, Here's the few steps to achieve the required output.

Go to Home - > Transform Data 

 

Open the Query which contains the column C_SerialNumber.

Go to - > Add Column - > Custom Column

New Column Name: CheckColumn

Custom column formula: Text.Contains([C_SerialNumber],"-")

Now click on OK.

 

Now again click on  Add Column - > Custom Column

New Column Name: NewC_SerialNumber

Custom column formula: if [CheckColumn] = false then "0" & [C_SerialNumber] else [C_SerialNumber]

Now click on OK.

Now, check on the formula bar, if the type isn't set to text then write it in a way as below screen short and click on the tick.

Please don't cross-post. Sorry, having trouble following, can you post sample data as text and expected output?
Not really enough information to go on, please first check if your issue is a common issue listed here: https://community.powerbi.com/t5/Community-Blog/Before-You-Post-Read-This/ba-p/1116882

Also, please see this post regarding How to Get Your Question Answered Quickly: https://community.powerbi.com/t5/Community-Blog/How-to-Get-Your-Question-Answered-Quickly/ba-p/38490

The most important parts are:
1. Sample data as text, use the table tool in the editing bar
2. Expected output from sample data
3. Explanation in words of how to get from 1. to 2.
