Hello everyone.
I'm recurring to the experts because this issue is driven me nuts. =P
I have a custom Table to save packing boxes information. The "PackBoxHdr" table contains a Primary Key that is a NoSerieMgt Value (Code 20), so it is working fine but also has a secondary Key that has a Document No. (Code 20) and a Carton No. (Int), when a user creates a new box from a page it runs a Codeunitfuntion to retrive the last packing box and create a new one for a Document No Value.
Code:
T_PFPack.RESET;
T_PFPack.SETCURRENTKEY("Document No.","Carton No.");
T_PFPack.SETRANGE("Document No.",TempSourceNo);
IF T_PFPack.FINDLAST THEN
TempCartonNo := T_PFPack."Carton No.";
TempCartonNo += 1;
...
WITH T_PFPack DO BEGIN
INIT;
"Internal Carton No." := TempCartonId;"Document No." := TempSourceNo;"Carton No." := TempCartonNo;
INSERT;
END;Now the issue is that if two users create a new carton for the same Document both user get the same Carton No creating two boxes with the same number. I have tracked down to believe that if both users the carton at almost the same time the second user gets a "ghost deadlock" and uses the cache information of the first one, so both users create the same number or at least this is my conclusion, also I've been looking for LOCKTABLE or a similar case but without any luck.
