Hi Priya,
What infortypes the user wants to trigger when the employee is shifted from one company code to another comp code. Maintain all those infotypes in your newly created action type. Like 0000,0001,0008(If any changes exists). These will be enough as there is only change in the company code.
Check whether the chart of accounts is one and same for the new company code. If it is different then you need to modify the configuration. GL Account mapping need to be changed.
