How to create a transaction line field that sources the conversion rate of the line's Unit of Measure?

AI generated answer (using internal Slack threads):

To create a transaction line field that sources the conversion rate of the line's Unit of Measure, you can use a client script to access the hidden field "unitconversionrate" on postsourcing of the item record. Here is a brief explanation: 1. Create a custom field on the transaction line level. This field will hold the conversion rate. Make sure to set the field type to decimal number. 2. Create a client script that will be triggered on the postsourcing event of the item record. In this script, you will access the hidden field "unitconversionrate" and set its value to the custom field you created in step 1. Here is a sample code snippet that demonstrates how to access the conversion rate:

javascript
function lineInit(type){
    if(type == 'item'){
        var conversionRate = nlapiGetCurrentLineItemValue('item', 'unitconversionrate');
        nlapiSetCurrentLineItemValue('item', 'custcol_your_custom_field', conversionRate);
    }
}

In this code, 'custcol_your_custom_field' should be replaced with the script id of your custom field. Please note that this field will not be shown until the record is saved. Also, other calculations at line level can access the hidden field if you need to do other things with it. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
