Why you can't close Shop Orders? Can you elaborate your issue? 

Do mean for a system reason or error that you can’t close the shop order?

IFS handles transactions on a date and time stamp basis that don’t require halting most transactions except maybe on the last day of the month for Finance to have time to take certain inventory snapshots and correct errors.

Your statement is not an expression of a question that can be answered.

You could follow the following steps to close the shop order.

If the question is related to DOP:

User has unpegged DOP Shop Orders, parents and all of the component shop orders. RMB on DOP Order Header to Close, and an Error is thrown “Unable to close due to not closed component DOP Orders

Answer : Close a Parent DOP Order while it has a Supply Component DOP Order .

Leaving a component supply order open while its demand order closed is not a valid situation.

So we either has to close all the Supply DOP Orders or select the Option Close/ Branch

Then system will close the Supply DOP Orders including the selected DOP Order.
