Hi Giang,

What version and patch level are you on? It always helps to include this information in the forum queries. Here are some items to look at while troubleshooting:

• Do you have any customizations? Try Development, Utilities, Dictionary, Difference analyzer, Objects (ACOMPOBJ) to identify object, window, screens differences between the X3 folder and the production folder. The X3 folder should have no changes.
• Did you recently upgrade or add any 3rd party products?
• If you upgraded and have 3rd party products or customizations, were those upgraded also.
• Run an engine trace to tract the transaction. See Sage knowledgebase article: How do I run an engine trace from within a function? (81615)
• With versions v12p20 and above, you cannot have a test folder. The test folder must be in a separate environment.
• Search the knowledgebase for articles with "non-existent label."  They might give you an idea.

I hope this gets you started!

pnightingale, thanks so much for your advice

Hi Open calculator, and type:  adxlog("TRA",2) This is going to create a trace file in TRA folder.

Reproduce again th error. When you get the error.
Copy the trace file
Search FINERR
The line just before you find FINERR is whicj is causing the problem.
Maybe you are lucky and could you get more info and If you are more lucky and you have the source of the traitment... ... you will now exactcly.

Open calculator again and type CloseLog(), this will stop trace.
Must be admin user if I remember well
