Hello, there's a unit cost issue with purchase orders in Technisoft Service Manager that we've been grappling with for a while and I wanted to see if this forum could assist.  When a line from a PO is only partially received (cost only) against a job in document entry, the unit cost of the item is changed in order to make the total cost of the COS equal the total cost of the line on the PO.  To explain the below screenshot, the PO has an estimate of 280 quantity at $81.50 unit cost, for a total cost of $22.820.00.  When this line is partially received with a quantity of 240, the unit cost it uses is $95.083333, for a total cost of $22,820.00.  The subsequent receipt from the line of 40 uses a unit cost of $570.50, again reaching an extended cost of $22,820.00.  Also below are screen shots of the item and supply settings.  Please let me know if you require any further information and thanks for your assistance.
