I did it in this way and I found out: timestamp of vcx (TYPE='V') records in pjx table was changed. I haven't checked 'Recompile all file' option. I didn't any changes to the source code before compilation. The other records of pjx table contained identical timestamp like table of pjx before compilation.
Compilation without 'Recompile all files' recompiles vcx libraries even if any the change was done in the source code.
I don't know to find a cause of this behaviour.
