I have simple Sharepoint list named Alist with lookup value column.

the lookup value column returns fields from other list named Blist. accidentally I have deleted this Blist and in Alist all lookup value disappeared, after I restored Blist but in Alist lookup values didn't restored.

is there some way to restore lookup values in Alist?

  • Have you enabled versioning in Alist? Have you any backups? – Zdeněk Vinduška Jan 8 at 12:23
  • no, version is not enabled and what type of backup do you mean? – Vaso Miruashvili Jan 8 at 12:32
  • Backup with DPM or some backing up program? The information is saved in List[ID] and because you haven't set that this is cascade lookup and you cannot delete this, so when you delete listB the values dissapear. > so you need backup of SharePoint for restore this values, otherwise you must set this manually again. – Zdeněk Vinduška Jan 8 at 12:34
  • It's separate program. You have your own SharePoint or in some company? Ask infrastructure of application manager.. – Zdeněk Vinduška Jan 8 at 12:46
  • I backup my sharepoint Blist but in A list there is no any lookup value. if I edit lookup column there is written "Get information from:" and no more information – Vaso Miruashvili Jan 8 at 14:33

ListB has now different GUID than the original one. GUID is used at ListA for referencing (original) ListB. You need to change referencing ListB GUID from ListA - this can be done but is a bit hard to do.

  • First, check out new ListB GUID Reference.
  • Save ListA as template (with content), save it on disk (stp packet)
  • rename *.stp to *.zip & unpack it.
  • from manifest.xml find the original referenced column and it's list GUID, change it to new ListB GUID
  • zip manifest.xml and rename *.zip to *.stp
  • upload file to list templates.
  • Create new list (new 'ListA') from this template -> reference should work now.

Have done this couple of times and it works.

  • It seems good way, now I got manifest.xml file so how can I find original referenced column and it's list GUID? – Vaso Miruashvili Jan 11 at 7:51
  • it is very good way but instance of .zip I have to do it with .cab, thank you – Vaso Miruashvili Jan 14 at 11:37
