We are running Sage 2018 (Build 30) (Product Update 3) - IC65A Inventory Control.  A User posted a Stock Transfer transaction from Location AAA to Location YYY for stock item 123456.  Then, before I/C Day end processing done, the User removed the Picking Sequence for Location AAA (i.e. changed from S88 to blank), changed the STDCOST, LASTSTDCOST and LASTSTDDAT for location AAA also.

So now the Stock Transfer transaction appears to stop Day end processing from completing, due to the 'cstp xIFO iloc mismatch error: missing ICCOST costing bucket' error.

Possible fix?
