When using standard cost transaction (example sale) System does the following validation:

Stock value/quantity on hand * sale quantity - Cost amount per unit * Sale quantity < 1 will allow the posting and post the difference to stock revaluation.  

By changing the code it is now allowing the difference to be 1.5. Possibly increasing the posting to revaluation for the item and warehouse to 1.5 and delaying the need to resettle until the 1.5 max is reached.

During Parallel running the system post the same revaluation multiple times (as the one revaluation is not posted included in the next sales transaction) and therefore this is causing imbalances between stock sub-ledger and GL.
