restore sharepoint list lookup value

Question

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?

Answer 1

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.
