This may need to be split into 2 bugs, but problems are related. The SIP2 specification lists two fields for holds requests: AB - item identifier AJ - title identifier 1 - When placing a hold via SIP we always place a title level hold but only use the 'item identifier' to determine the biblio 2 - When cancelling a hold we use the 'item identifier' to identify the item and will only cancel an item level hold We should allow the use of the 'title identifier' for placing holds, and we should place an item level hold if 'item identifier' is passed or title level if 'title identifier' is passed with no item identifier We should do the same for cancelling.
This will be a bit messy to fix, but shouldn't be too difficult. Will require changes to ILS.pm, Hold.pm and Item.pm in C4/SIP. The bigger issue is, should we retain the legacy behavior? If so, we will need a new account parameter.
