Tcode:ME21N
创建PO=CCSTO，如果是MTS PO type 选ZSTO
Supplier = CW30, Fill in Purch. Org. , Purch. Group, Company Code
Fill in material , Qty , Plant, Store location
Fill in Batch.
Fill in Issuing Store location
After save, the CCSTO will be generated, if CW30 = WOFE have enough stock , delivery schedule with committed Qty, if no committed Qty, can't go to next to create DN
Tcode：VL10B . 创建CCSTO DN, fill in Purchasing document
Highlight line item and click “Background”
If you can see greenlight, that means CCSTO DN has been created. please double click line , it will go to ME23N , you can see CCSTO DN under by "Purchase Order History"
To complete CCSTO PGI, use Tcode:VL02N or click CCSTODN by PO page
点击 "post good issue", PGI就完成了，也就是说CW30=WOFE的库存已经扣掉。PGI的日期可放可不放，不放系统就默认当天。BATCH 和SLOC 这两个地方，如果CCSTO 有填就会自动带到CCSTO DN，如果CCSTO没有填，那么CCSTO DN需要维护。
下面是CW20=TOIF公司做收货，需要用Tcode:MIGO
选择A01 Goods Receipt, 放CCSTO PO，GR goods receipt = 101, 然后“enter”
点击“Item OK”, 确保行上是打勾的，然后点击“Check", 如果没有问题，一般会出黄灯提示。如果有问题会出红灯阻止不给收货。
下面是Check and Post 执行后的画面
以上步骤完成可以回去ME23N查看CCSTO “Purchase Order History", 看到这个就是整个CCSTO完成，从CW30转到CW20的流程
同时也可以去MB52查库存
