[Koha] homebranch, holdingbranch, transfers

[Frédéric Demians]

Your may try this. You need a third item's field: sourcebranch.

(1) When you move the batch of items from library A to B, create a text file
containing items' barcodes. Then batch modify those items:

  sourcebranch=A
  homebranch=B
  holdingbranch=B

(2) During the exams period, no transfer to A will be done at check-in. If the
check-in is done at library A or C, the transfer to B will be proposed, which is
what you want.

(3) When you move back the batch of items to library A, do a batch modify
using the text file create at 1:

  sourcebranch=A
  homebranch=A
  holdingbranch=A
