Erply API version 1.5.10

Reasons for tax exemption (purpose = "TAX_EXEMPTION") can now be retrieved with API getReasonCodes.
Added configuration parameter zreport_hide_drawer_openings. Set the parameter to 1 if you do not want to see the "drawer opened" events listed in the Z Report.
Fixed: In some cases, API calculateShoppingCart calculated an incorrect cart total when buying a fractional quantity.
Fixed: In some cases, API calculateShoppingCart made a 1-cent error when applying promotions "Get $ off the entire invoice".
Clarified and improved the behavior of the following two promotion features in API calculateShoppingCart:
- A promotion that gives % or $ off of multiple items in the cart;
- The setting that discount should apply to the least-priced item in the shopping cart. (There is a check box on promotion card for that.)
Input parameter "productIDs" added to API getSalesReport. (This allows filtering invoice rows by multiple products, not just one.) This change also requires back office version 4.3.18+.
New report variant SALES_BY_MATRIX_WITH_DRILL_DOWN added to API getSalesReport.
Support for Element TriPOS additional data added to API getPayments and savePayment.
