how can i add a custom field on the assembly build lines

AI generated answer (using internal Slack threads):

To add a custom field on the assembly build lines, you would typically create a transaction line field and check "applies to work order". However, based on the conversations, it seems that adding a Custom Transaction Line field on the Assembly Build page through basic customization is not possible and is still being filed as an enhancement. As an alternative, you can manipulate the JSON at the customer header field to look at the line level. You can also use the

Sublist.addField

method as suggested in the conversation. However, this method is not directly applicable to the assembly build lines. When it comes to setting inventory detail information to non-serialized items using SuiteScript while creating Assembly Build, you should avoid using dynamic mode methods like

selectLine

when working with records in standard mode. Instead, use methods that have a line parameter, like

Record.getSublistSubrecord

. However, you can't set inventory details in a

beforeLoad

entry point and you can't set sublists on the subrecord in client script. The closest you can get via SuiteScript is a client script deployed on the inventory detail record. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
