I have a client who would like to be prevented from being able to invoice into negative stock. I believe there is a script available that does this. Can anyone help me?

Here it is:

Please note that this script requires CAPITAL 7.41 maintenance release C or higher. The Echo() statement is actually a single line.

If .Not. ReadTranValue("NEW")
Return TRUE
Endif

Declare nQty Type Number

lTranIsOK := TRUE
nCount := 0
nMaxCount := ReadItemValue("STOCKID", -1)

:Loop
nCount := nCount + 1

If nCount > nMaxCount
Goto End
Endif

If IsEmpty(ReadItemValue("STOCKID", nCount))
Goto Loop
Endif

If .Not. Stock->(Find(ReadItemValue("STOCKID", nCount), 3))
Goto Loop
Endif

nStockIn := StockGetQuantity(FALSE)
nQty := ReadItemValue("QTY", nCount)

If nQty > 0 .And. nQty > nStockIn
Stock->(Find(ReadItemValue("STOCKID", nCount), 3))
Echo("Sorry you are trying to invoice more than is available in stock for stock item " + Alltrim(Stock->Name) + ";;" + "Physical Stock: " + NTrim(nStockIn, 10, 1) + ";To invoice: " + NTrim(nQty, 10, 1),, TRUE)

lTranIsOK := FALSE
Goto End
Endif

Goto Loop

:End

Return lTranIsOK
