How to Bring Underscore in Flow Approvals Connector

[guna_win13]

My goal is to get this Underscope. Sadly, this trick does not support me,...🙄

How do I bring this Underscore Format MEP's Name into Approval Connector?  

My MEP Name format -
PCBA_Chennai_232
MECH_Zhuzhi_832
PCBA_Guad_988

Hi @guna_win13,

Try string concatenation: concat('_', variables('myVar'),'_')

@johnokeeffe  what is my issue here..🙄
i wrote this. 

concat('_',variables('MEP_Name'),'_')

@guna_win13 you can't self reference the variable. Which means you can't set the variable while also referencing the variable with the same name.

Move the code from the variable to the start approval action title instead and it should work or just initialize a new variable with a different name.

Could you please share screen shot with this method. So next it would be helpful to see this...

hi @guna_win13 

Instead try to concat in compose action so you can avoid self reference issue.

Thanks

Hi @guna_win13 

If I understood you rightly you're trying to set _ (underscore) in the details section of Approvals

details section accepts markdown language to escape and use underscore can you try like this?

concat('\_',variables('MEP_Name'),'\_')

P.S. This valid only for markdown but for other cases backslash is not needed.

for ex: to write PCBA_Chennai_232 we need to compose as PCBA\_Chennai\_232 in markdown

@Shujaath_Khan  - I thought is this didn't achieve it in the Power Automate Flow,.. like I have more than 200+ Mep Code in my Share point List, automatically, I will get this code, instead manually entered PCBA\_Chennai\_232 like that

for ex: to write PCBA_Chennai_232 we need to compose as PCBA\_Chennai\_232 in markdown

concat('\_',variables('Code'),'\_')
