[Koha] adding existing items to acquisitions

[Giuseppe Angilella]

Hi,

how can I add existing items to existing acquisitions?

The normal procedure would be to first "order" an item within an 
acquisition's basket, and then have it "received". But I am trying to 
reconstruct past acquisitions (for the sake of my library's records), that 
had been dealt with outside Koha.

Existing items are already populated with costs and source of acquisition.

(I wouldn't mind acting directly on the database by means of mysql 
commands.)

(Batch procedures would be helpful, as I have plenty of items to be added 
to acquisitions, and I can easily select their itemnumber into groups by 
means of appropriate mysql clauses.)

Many thanks.

Giuseppe.
