ERPLY Back Office version 4.3.24

Fixed: when a matrix product with repeating dimensions had been defined (eg. color, color, size), the variation picker on invoices and purchase invoices allowed to select non-existing combinations.
Fixed: when entering new matrix dimension values, code was not saved.
Fixed: in product import, if "Price list price" field has been left empty, ignore that value. (Previously, Erply imported it as $0.00.)
Check box "Allow the same items to trigger other promotions after this promotion has been applied" added to promotion card. This feature (promotion stacking) requires API version 1.5.15+.
