BAPI_ACC_DOCUMENT_CHECK,
BAPI_ACC_DOCUMENT_POST ，
会走校验，但是不走替代。

校验validation
上图里走校验。
上图3，先走check如果有标准报错，则退出function AC_DOCUMENT_CREATE，回到上图1，不走header校验，在perform check_cobl中走item校验。
如果没有标准报错，则在上图3 function AC_DOCUMENT_CREATE中走perform document_create using split, 然后走下图1调用FI_DOCUMENT_PROJECT，perform document_validation中走 FI_VALIDATION_HEADER，FI_VALIDATION_ITEM，FI_VALIDATION_DOC(完全凭证，回车不进，保存进)
