I have 500 Item Receipt transactions that must be updated. There is a custom field sourcing its value from the Project list. In those 500 IRs, there are 65 unique projects that must be replaced with another projects (correct one). There is a one-to-one relationship between the wrong project and the correct project. Project A will always be replaced by Project AA, Project B by Project BB and so on. Can someone suggest what is the best approach to achieve this through script? Or maybe a helpful documentation? I am not yet that familiar with arrays in NS if it needs it, so a sample or an article would be very helpful. Thank you.

Probably quickest to just CSV it

There is no Item Receipt option for CSV import. If there is, I'll be the happiest person today! Lol

Damn :)

Check celigo integrator. I believe they give you 1 free flow and this may help you. There is a small learning curve but their help section is pretty good. When you do the free trial use data loader as your option.

@Luis Celigo’s CloudExtend Excel for NetSuite can help here. Item Receipts are supported. Should be piece of cake.
