Purchase line can be modified after the PO is released?

koalado

After the PO is approved, the PO status change to 'Released'. But the buyer still can change the PO lines (Quantities, Price and etc). I checked their rights on table 'Purchase Line'. all the buyers have insert, modify and delete rights.
I'm Super. When I test it with my account, it will prompts error as what I expect. "The PO must be Reopened ".
Please help! Thanks

The only thing I can think of:
In table 39, when you change a field, it calls function "TestStatusOpen()". This functions calls "GetPurchHeader()" and if the the header is still the same as the one in the last "GetPurchHeader()"-call, then Navision doesn't get the purchase header anymore.

Maybe the release of the purchase header has been changed from calling the codeunit in the properties of the menu-item to calling it with C/AL code. In this case, try to do a CurrForm.UPDATE(FALSE) after calling the codeunit.


If previous trick doesn't work, try this: in T39, function "GetPurchHeader()" in stead of the code like:

TESTFIELD("Document No.");
IF ("Document Type" <> PurchHeader."Document Type") OR ("Document No." <> PurchHeader."No.") THEN BEGIN
  PurchHeader.GET("Document Type","Document No.");
  IF PurchHeader."Currency Code" = '' THEN
    Currency.InitRoundingPrecision
  ELSE BEGIN
    PurchHeader.TESTFIELD("Currency Factor");
    Currency.GET(PurchHeader."Currency Code");
    Currency.TESTFIELD("Amount Rounding Precision");
  END;
END;

Try:

TESTFIELD("Document No.");
PurchHeader.GET("Document Type","Document No.");
IF PurchHeader."Currency Code" = '' THEN
  Currency.InitRoundingPrecision
ELSE BEGIN
  PurchHeader.TESTFIELD("Currency Factor");
  Currency.GET(PurchHeader."Currency Code");
  Currency.TESTFIELD("Amount Rounding Precision");
END;

But this has the problem that it will always get to the disk to get the purchase header.

Maybe the buyer Reopen the PO and Released it again?

Not a very bright answer, I know

Actually, it is a very good question. It is so obvious, I didn't even consider it.
But with users we should always start with the most obvious questions.

Hi all:
Problem solved. I traced the program as you mentioned and found only PO's status <Type::Item> and <Type::"Fix Assets"> will be checked if it's Open when we try to modify purchase lines. But what I want is another type "G/L Account" should also be checked. So, I add that type to function <TypeStatusOpen>. Yeah, that works.
Thanks again.
