sap 秀才 -mm 学习指南 -4.采购合同contract and release order为了降低采购成本、维护与供应商的长期合作关系、简化采购中间环节控制（例如反复的询价报价），企业可以与供应商签订长期采购合同contract 。在产生了实际的物料需求时，可以根据采购合同issuerelease order（即 create release order against contact）。1. 创建采购合同（ tcode: me31k）path: logistics-material management-purchasing-outline agreement-contract-create创建 contract 有很多的方式：manual 、copy document、reference to preq、reference to rfq。agreement type：数量合同：目标数量已知，系统强制要求输入target quantity。价值合同：目标价值已知，系统强制要求输入target value 。quantity contracts-可编辑修改 -use this type of contract if the total quantity to be ordered during the validity period of the contract isknown in advance. the contract is regarded as fulfilled when release orders totaling a given quantityhave been issued.value contractsuse this type of contract if the total value of all release orders issued against the contract is not to exceeda certain predefined value. the contract is regarded as fulfilled when release orders totaling a givenvalue have been issued.输入采购组织和采购组，enter ，意思是设置阶段我们没有指定采购组织和公司代码的关系，在这里输入公司代码，enter ，在这里主要输入validity end=2009-12-30，通常采购合同都是一年一签。enter ，输入物料 b-16mnr-12 ，target qty = 20000kg， net price = 6.6 （价格上当然要比前面的6.7rmb/kg优惠一点）。 save ，系统提示创建了数量合同4600000004 。执 行 me35k 来 release contact ，点击 release + save动作，批准采购合同。2. 创建 release order（ tcode: me21n ）path: logistics-material management-purchasing-purchase order-create-me21n参照 contract 创建的 purchase order都叫做 contact release order，简称 release order，也可以叫做call-off order 。over the contract validity period, certain quantities of the materials or services covered are released(called off) against the contract as and when required through the issue of purchase orders referencingthe latter. such purchase orders are thus termed contract release orders or simply release orders.(outside sap, particularly in the uk; they may also be referred to as call-off orders.)在左边查询出之前创建的采购合同4600000004 ，拖放到 header 上方的小车内 ，系统将自动创建出一张采购订单，输入本次采购数量120kg ，当然价格6.60 可以根据需要进行二次调整（默认带出的是采购合同的 net price ）。从这里也可以看出对于数量采购合同，target quantity是一定的，但是value
