Currently I’ve been following as per suggestion by the Developer team to link between Invoice and Purchase Order to Cost Center by customizing the Sales Invoice and Purchase Order form includes the option to choose the Cost Center. But I realised it is not in drop down value as I initally setup under my Account setting for Cost Center.
My setup is based on below format
How am I able to set it on drop down option which is already set under Account section for Cost Center? If possible I try to avoid scripting as I’m not an experts for the program scripting
