由MRP产生的采购申请科目分配类别如何自动带Q
用户反馈跑完MRP后，项目库存采购申请有的科目分配类别带Q，有的不带Q，截图如下：
这个PR科目分配类别是自动带Q的
下面这个PR科目分配类别是不带Q 的
查询发现，能自动带Q的PR的物料，在MRP4视图Individual/coll.字段由2改为了1，
而PR没有自动带Q的物料在MRP4视图Individual/coll.字段维护的是2 .需要更改为1
由于工单生成预留之后, PR已经生成了, 所以MD04找到对应工单
CO02修改工单在special stock indicator字段输入2, 表示project stock, 然后MD02重新运行MRP就可以了，就可以看到PR科目分配类别带Q 了。
那么这个Individual/coll.字段维护1和2分别有什么作用呢？
Dependent requirements ind. for individual and coll. reqmts
Indicator determining whether the following requirements are allowed for the dependent requirementsof the material:
- Individual requirements
- Requirement quantities of the dependent material are stated individually.
- Collective requirements
- Requirement quantities of the dependent material are grouped together.
Use
You can maintain this indicator in the following places:
- In the material master record
- For the explosion type of the BOM item (in Customizing for Basic Data in Define Explosion Types)
The setting for the explosion type overrides that in the material master record.
Dependencies
If the material is assigned to a material type that does not allow quantity-based inventory management in this plant, you can set the indicator to individual requirements only.
If the stock is to be managed in sales order stock or project stock, the indicator must be set to one of the following options:
- Individual and collective requirements
- Individual requirements only
If a material managed in project stock is to be procured from another plant using a cross-company-code stock transport order, the indicator must be set to 2 (collective requirements) in the issuing plant because, in this specific context, individual project stock management is not possible in both plants.
由上面SAP官方字段解释来看，当物料用于销售订单库存和项目库存的时候，Individual/coll.字段必须维护为空或者为1.
