143 $biblio->can_be_transferred({ to => $to_library, from => $from_library })
145 Checks if at least one item of a biblio can be transferred to given library.
147 This feature is controlled by two system preferences:
148 UseBranchTransferLimits to enable / disable the feature
149 BranchTransferLimitsType to use either an itemnumber or ccode as an identifier
150 for setting the limitations
152 Performance-wise, it is recommended to use this method for a biblio instead of
153 iterating each item of a biblio with Koha::Item->can_be_transferred().
155 Takes HASHref that can have the following parameters:
156 MANDATORY PARAMETERS:

160 # holdingbranch are considered
