Sales Lines are being imported through a Configuration Package where fields like Item No., HSN/SAC Code, Quantity, MRP, and GST Group Code are uploaded. When the Item No. is imported, the system automatically loads the default GST Group Code (for example 18%) and HSN from the Item Card. After that, when the MRP is imported, the system calculates MRP Excl. GST based on the item’s GST rate. The requirement is that if the GST Group Code is set to GST-0 through the Configuration Package, then the GST amount on that Sales Line should become 0, the same way it works during manual entry. However, in the current behavior, even after the GST Group Code is updated to GST-0, the system still calculates GST on the line because the GST recalculation trigger does not run during the Configuration Package import. Due to this, the previously calculated GST is not cleared and the Sales Line shows an incorrect tax amount. The expected behavior is that when the GST Group Code is updated through the Configuration Package, the system should automatically recalculate GST and update the GST amount accordingly, which should be 0 in the case of GST-0.
