Solution:
1. Do not attempt to change costing!
2. However, should you need to change costing, change only data on the
current day. It is wise to change costing for the approved document ony if you
are sure what happened with this document or goods after it was already approved
and if you usually run these procedures once again. Moreover, you need to keep
in mind the data which depend on costing. These depend on factors too numerous
even to enumerate them so TAKE CARE when making changes! In this way it is for
example required to recalculate prices appearing in valuation if any
transactions (sales of goods, transfer to consignment or commission,
interwarehouse transfer) were made with these goods or goods of this kind (depending
on the stock valuation method selected). If it was posted automatically, it
needs to be reposted, etc..
