AI generated answer (using internal Slack threads):

Based on the conversations, it seems that the error message

Invalid API usage. You must use getSublistValue to return the value set with setSublistValue

is a known issue in NetSuite. This error typically occurs when trying to retrieve a value that was set using

setSublistValue

without first using

getSublistValue

. One workaround mentioned in the threads is to use

getSublistValue

before using

setSublistValue

. This is because

getSublistValue

may not be available in create mode, and you might need to find another way to get the information you're trying to retrieve. In addition, it was mentioned that

setSublistValue

might not work if the record object is in dynamic mode. The solution to this issue is to set

isDynamic

to

False

when using

setSublistValue

. Furthermore, in a client script, you can use both 'current' mode APIs and standard. This can be done by using both types of functions in the script, for example,

getCurrentSublistValue

and

getSublistValue

. However, to set a sublist value, you might need to select a line, use

setCurrentSublistValue

, then

commitline

. This is because

setSublistValue

might not work, and using the aforementioned method might take a bit longer. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
