RE: SHARING ITEM LIST IN DIFFERENT COMPANIES
hello
but you are working with nav
did you create a custom table? or are you trying to put the DataPerCompany on the standard item table? this is not recommended
if you create a YourItem table then in NAV you can set it as DataPerCompany=yes so that you have data common to all companies
but the solution I recommend is to make or have made a development in which you simply synchronise items from one company to another
an idea would be to bind to the OnAfterInsertREcord event of the item table and at that moment with a changecompany transfer it also to the other company

remember that validates, however, do not click with the changecompany
check my answer if it helped you, thanks
