(8) two number ranges, external and internal, per group
二、如何使用号码范围
2.1 确定号码范围的类型并创建新的号码范围对象(SNRO)
需要多少个号码范围: 1, 2 或者更多?号码范围是否需要子范围对象 (如:company code, plant, controlling area等等)?
号码范围是否需要分组 (如:物料类型)?
如果需要分组,那分组的是否需要子范围对象?
号码范围是否需要区分财务年度?
2.2 维护号码范围对象的间隔;
3.3 在程序中使用号码范围的函数进行记录编号或检查可用号码;
三、号码范围的函数简要说明
3.1 函数组(SNR0)
This function module displays the groups which exist for a particular number range object, with their number range intervals.
After return, the return code chosen by the user (Back or Cancel) is available.
This function module displays all elements, which are assigned to a number range interval.
After return, the return code chosen by the user (Back or Cancel) is available. (only object types 4-8)
This function module enables you to copy number range objects from groups and intervals of an existing sub-object of a given number range object to another of its existing sub-objects.
After return, the return code chosen by the user (Back or Cancel) is available. (only object types 4-8)
This function module provides a dialog box in which the user can enter a sub-object for a given number range object. If the specified sub-object already exists for the number range object, it is returned in the export parameter. If it does not exist, either an exception is raised or the return code "A" for user abort is returned.
With this function module the maintenance dialog for number range intervals for a given number range object is offered. A parameter specifies the processing type. Possible processing types are:
- Maintain intervals
- Change number status
- Display intervals
- Create new groups (only for object types 2 and 3 and 5-8)
The dialog path is determined by the object type.
After return, the return code chosen by the user (Back or Cancel) is available.
This function module is the maintenance dialog (Create, Change, Display) for number range groups for a given number range object. A processing flag determines whether the object is to be displayed only or whether it can be maintained. Groups are deleted by deleting their intervals.
After return, the return code chosen by the user (Back or Cancel) is available.
3.2 函数组(SNR1)
With this function module, you lock the number range object which is to be maintained, and its groups and intervals, for access by other users. Lock errors are returned as exceptions.
With this function module, you unlock the number range object which has been maintained.
This function module gets the elements which are assigned to a particular number range interval for a number range object. The elements found are passed in a table. Errors are returned as exceptions.
With this function module you can find element texts in the specified language for a given number range object. The texts are returned in a table. Execution errors are returned as exceptions.
This function module gets information about groups and the associated group and element texts for a specified number range object. The information is put in a table. The table can be used to change the element assignment or the group text. The change request is to be passed to the function module NUMBER_RANGE_GROUP_UPDATE.
Errors are returned as exceptions.
With this function module, already assigned elements can be assigned to other intervals, or the assignment can be withdrawn. Group texts can also be maintained. All change requests are checked. Request errors are returned in an error table.
The changes are passed in an internal table and are copied into the local memory of the function group.
Before you call this function module, you must lock the number range object in question with NUMBER_RANGE_ENQUEUE, and unlock it again with NUMBER_RANGE_DEQUEUE after writing the changes to the database.
To copy the contents of local memory to the database, call the function module NUMBER_RANGE_UPDATE_CLOSE.
This function module gets the existing intervals to a given number range object, and puts them in a table. The table can be passed to the function module NUMBER_RANGE_INTERVAL_UPDATE to change intervals.
With this function module you maintain intervals for a given number range object.
The changes are passed in an internal table, and are copied into local memory.
Before you call this function module, you must lock the number range object in question with NUMBER_RANGE_ENQUEUE, and unlock it again with NUMBER_RANGE_DEQUEUE, after the changes have been written to the database.
To copy the contents of local memory to the database, call the function module NUMBER_RANGE_UPDATE_CLOSE.
This function module gets information for a given number range object. This information is put in a table structure, which must be declared like the table structure INROI.
This function module gets the existing sub-objects of a given number range object, and puts them in the table passed.
This function module gets information about the existing sub-objects of a given number range object. This information is put in a table structure, which must be declared like the table structure INROI.
With this function module you write changes which have been made to local memory to the database, with NUMBER_RANGE_GROUP_UPDATE and NUMBER_RANGE_INTERVAL_UPDATE. After calling this function module, you should unlock the changed number range object.
With this function module, you can initialize local memory if you want to discard the changes which have not yet been copied to the database.
3.3 函数组(SNR2)
This function module provides all the screens needed to maintain a given number range object, with the possibility of branching to interval maintenance and change document display.
An export parameter states which action the user has performed with the number range object.
With this function module, you write all changes to a given number range object, which were put in local memory with NUMBER_RANGE_OBJECT_UPDATE, to the database. If intervals are affected by the changes, they are updated. Change documents are created for all changes. A flag states whether intervals have been updated.
With this function module, you can delete either the whole definition of a given number range object, including texts, or only the texts. The deletion is performed directly in the database.
The function module provides no connection to the correction and transport system.
With this function module, you initialize local memory for a given number range object.
You only need this call when you offer number range object maintenance in a user transaction, in which you want to provide the possibility of canceling changes which have not been saved.
This function module gets a list of all number range objects with their texts and attributes. The information is put in a table.
The contents of local memory are not taken into account.
This function module gets the texts and attributes of a given number range object. The records returned can be used for changes with the function modules NUMBER_RANGE_OBJECT_UPDATE and NUMBER_RANGE_OBJECT_DELETE.
This function module copies new number range objects or changes to existing number range objects into local memory, after error checks.
The function module does not provide a connection to the correction and transport system.
