为移动类型分配科目分组中“价值串”一栏怎么用。

画面.doc 在“为移动类型分配科目分组”中，有一画面。 疑问：其中的“价值串”一栏，是何用处？在何处维护（输入）的？ 谢谢！！！

The R/3 System automatically determines the value string assigned to a specific transaction. It depends partly on entered parameters manully and partly on parameters derived internally by the system ( for example: movement type, material's value & quantity update,special stock id,movement id,purchase order type,acct assgt categort). The value string contains all posting transactions that are possible for a certain transaction.The program decides which of these posting transaxtions lead to G/L acct postings in individual cases.

为什么没人敢回答，webmaster为什么不帮助一下？？
