SAP的一般盘点单创建使用的事务码是MI01，此事务码只能单个输入进行创建，在实时的时候，很多企业都会使用自开发程序来批量创建盘点单，以满足符合本企业盘点的程序
SAP的盘点过程分为三个步骤：
1、 创建盘点单；
2、 输入盘点结果
3、 盘点单差异过账
这三个步骤对应了三个不同的BAPI,
1、 盘点单创建— BAPI_MATPHYSINV_CREATE_MULT
2、 盘点结果录入— BAPI_MATPHYSINV_COUNT
3、 盘点单差异过账— BAPI_MATPHYSINV_POSTDIFF
一些公司为了简化流程，会将这三个步骤简化成两步：创建盘点、盘点结果录入和过账合并成一步
盘点单的底表为：IKPF 和 ISEG
BAPI_MATPHYSINV_CREATE_MULT的实现过程如下：

BAPI_MATPHYSINV_COUNT的实现过程如下：

BAPI_MATPHYSINV_POSTDIFF的实现过程如下：
