Mainenance Module ERROR AFTER CHANGING FROM SALES ORDER TO INSTALLATION NOTE

I am getting the error afer I did some coding in the Maintenance Module in replacing FROM SALES ORDER TO INSTALLATION NOTE.

**Any further coding I have to update in py files?

This is really difficult to say anything about the error without seeing your code changes. Please share you changes.

Thanks,

Please find the below code as I have done the coding only in the .js file of he Maintenance Module.

Hi Nabin,

Thanks

Can you please clarify the line of coding to be changed.
Hope I do n’t need to change anything in the DB.

Hi, I am facing similar kind of issue like pymysql.err.InternalError: (1054, “Unknown column ‘tabGate Entry.transaction_date’ in ‘field list’”) while selecting Get items from button. What would be the solution for this?

Regards,
Nivedha

i have mapped Purchase Order doctype to another doctype which is Gate Entry through Get items custom button and then in Purchase Receipt i kept Get items from button and here i mapped Gate entry doctype and Purchase Receipt doctype button is visible by selecting on Get items from button popup it throws error like pymysql.err.InternalError: (1054, “Unknown column ‘tabGate Entry.transaction_date’ in ‘field list’”). I don’t want Purchase Order Transaction Date here. how can i rectify it?
