Openlab CDS 2.5 Acquisition Method status cannot be changed

Hello everyone,

We have a problem with the acquisition methods on GC, but not on HPLC.

When we want to change an acquisition method that is in "approved" status to "generic" status in order to modify it, it is impossible to do so because the box is grayed out, and the following message appears "Method status cannot be modified while there are pending changes. Reopen the method to modify the status".

The problem is not related to privileges because in HPLC it works, with the same profile. We have the problem only in GC (GC/FID/liquid injector).
Moreover, we have already succeeded in performing this action in the past, so we really don't understand.

We have closed all open methods, restarted PCs, AICs and instruments, but it has not changed anything, the problem persists.

Do you have any idea what it could be?

Thanks in advance for your help.


  • Hi Ludivine,

    I would check the Privileges in the Control Panel for that instrument. I have just checked and you should be able to do what you want on both LC and GC, if you are using the same user and project. So I suspect the privileges at the instrument level have been changed.

  • Hello Ludivine, 

    Method editing privileges apply to the project as you suggest, not the instrument, so the behavior you describe is strange. I am using a 7890 GC and am able to modify the method status at will given the permissions. Can you perform a Save As on the method to save it as a new method file? This would default the method status to generic for the new file.
