Summary

0016521: Wrong quantity in Suggested Purchase Order when running Purchasing Plan

Description

Wrong quantity in Suggested Purchase Order when running Purchasing Plan: Quantity of suggested purchase order should be sum of quantities of pending sales order

Steps To Reproduce

1. Master Data Management || Product || Product : search for Hammer
2. Master Data Management || Product || Product >> Purchasing : add record for Mcgiver with "current vendor " checked
3. Master Data Management || Product || Product >> Org Specific : add record for Main and Capacity=10000 and Safety Stock=0
4. Warehouse Management || Transactions || Physical Inventory || Header : set stock for hammers to 0 units
5. Material Requirement (MRP) || Transactions || Purchasing Plan || Header : create record for
  - Main
  - 02/03/2011
  - time horizon=10
  - safety = 0
  - vendor= mcgiver
  - product=hammer
Material Requirement (MRP) || Transactions || Purchasing Plan || Header >> Lines : add lines
  - line1: hammer + quantities= 0 + dates=02/03/2011 + type= Stock + fixed=Y
  - line2: hammer + quantities= 0 + dates=02/03/2011 + type= MinStock + fixed=Y
  - line3: hammer + quantities= -5 + dates=02/03/2011 + type= PendingSalesOrder + fixed=Y
  - line4: hammer + quantities= -3 + dates=02/03/2011 + type= PendingSalesOrder + fixed=Y
  - line5: hammer + quantities= -2 + dates=02/03/2011 + type= PendingSalesOrder + fixed=Y
6. Come back to Purchasing Plan header and press"Process Purchase Plan". Relize that line of type "Suggested Purchase Order" has Quantity different from 10 (which is sum of 5+3+2)

Proposed Solution

in line 139 of function mrp_purchaseplan should be added
v_neededqty_old := v_neededqty_new;
because actually this variable only is being updated when executing "IF" clause but not "ELSE" clause.

As same block:
v_neededqty_old := v_neededqty_new;
v_qty_old := v_qty_new;
v_stock := v_stock + v_qty_new;
will be executed in IF and ELSE they can be put outside
