Change "Direct Unit Cost" in a released "Purchase Order"
That is not possible!
Do you really think so?
Yes?
So did I until a few hours ago when I got an email saying that it can be changed. Maybe some unexpected side-effect of some customization with G/L accounts we made?
First thing: lets see what it does in CRONUS. Create new "Purchase Order". Create new "G/L Account" line. Release the order. Change the "Direct Unit Cost". Error……….. I should have an error!……… Where is the error?…….. Why is there no error?……… Is it a standard CRONUS?…….Yes. Definitely nothing changed…….
Let’s start debugging.
Ahah, the call to function "TestStatusOpen". This should block it.
This is the code of function "TestStatusOpen" in 2009SP1W1:
IF StatusCheckSuspended THEN
EXIT;
GetPurchHeader;
IF Type IN [Type::Item,Type::"Fixed Asset"] THEN
PurchHeader.TESTFIELD(Status,PurchHeader.Status::Open);
Do you see why it doesn’t block?
Correct: If Type is different from Item and different from "Fixed Asset" it doesn’t test the status of the header! Commenting the <IF Type IN [Type::Item,Type::"Fixed Asset"] THEN> fixes the problem.
I have to admit that I didn’t check all functionality to see if it blocks something else somewhere else.
That’s dangerous. If a purchaser creates a line with a G/L Account, and he needs to go through the Approval process. After it is approved, he can still change the "Direct Unit Cost" without having to re-approve it again.
And we have the same problem (and same solution) with Sales Order lines.
