hi,
Rescheduling sales and stock transfer documents: by material
Description
The 'Rescheduling' program (SDV03V02) processes sales document items that are contained in the item directory for the material. It takes into consideration open items and schedule lines from stock transfer items, stock transfer scheduling agreements and purchase order requests (items only), referred to hereafter as stock transfer documents, for the materials.
All sales documents for the material that are still open are selected. This means that the material index must be activated for at least all sales document types, whose items may have requirements. All stock transfer documents or items for the material that are still open are also selected. Open in this case means for example, that there is no deletion indicator, that the item from a stock transfer purchase order request cannot be labeled as completed or that the quantity delivered and posted to goods issue for the item in a stock transfer purchase order is the same as the amount ordered. An availability check can only be carried out if a checking rule is assigned to the document type - if this is not the case, the document or document item is not checked.
Checking rule 'A' is used as a basis for rescheduling sales orders (exceptions to this are rush orders they use checking rule B, and orders with individual customer stock; they use checking rule AE). Stock transfer documents use the checking rule that is assigned in Customizing for Purchasing. It is important that the scope of checks is consistent for both the stock transfer documents and the sales documents and that they do not exclude each other, as this can lead to incorrect test results. An example of an incorrect setting would be: The scope of check for checking rule 'A' checks delivery schedules for stock transfer purchase orders and stock transfer purchase requests, however the scope of check for the checking rule for the stock transport scheduling agreement does not.
The items and schedule lines found in the selection are sorted according to 'Priorities' - document category, delivery priority, creation date of the item or schedule line (for stock transfer purchase orders and delivery plans) entered on the selection screen or according to the schedule line date of the earliest schedule line with order quantity, document number and item number and then transferred to the availability check. Priority 1 is highest priority and priority 5 the lowest. Stock transfer purchase order requests are sorted after stock transfer purchase orders and scheduling agreements, as they are less binding. This means that when you have identical sort criteria such as delivery dates, the stock transfer purchase order item is checked first and then the item from the stock transfer purchase order request.
The preset option 'Unconfirmed documents required' only carries out rescheduling for materials for which there is at least one unconfirmed transaction.
You can use the parameters 'Sorting criteria delivery date' to define whether sorting is carried out with the order quantity after the creation date of the item or the delivery date of the earliest schedule line.
If you mark the 'Simulation' field, the checked documents are not saved. Instead a results list is generated and saved. However, the availability check for the corresponding documents continues as if saving has taken place already, that is, that the simulated list corresponds to the actual one.
Under 'Options' on the selection screen, specify whether sales documents and/or stock transfer documents should be processed. For stock transfer documents you can enter whether stock transfer purchase orders and scheduling agreements should be processed at item or schedule line level:
Processing at item level:
All open schedule lines for the item are read and collected, then transferred to the availability check. To sort and prioritize documents, you do not need each individual schedule line. It is sufficient to have the item or data from the first schedule line. All open schedule lines for the item are processed and checked.
Example of processing at item level:
Sorting: Date (Delivery date first schedule line) - Document number - Document item
Doc. cat. Doc. number Doc. item Doc. schedule line Delivery date PO 4500000012 10 0001 26.01. PO 4500000012 10 0002 26.02. PO 4500000025 20 0001 28.01. PO 4500000025 20 0002 02.02.
You can see that the second schedule line for document 4500000025/20 from 02.02 was processed after the second schedule line for document 4500000012/10 from 26.02. This is because all open schedule lines for an item are read and processed. The first schedule line from 4500000012/10 has the earliest delivery date, therefore it has priority.
Processing at schedule line level:
Each open schedule line for an item is entered in document sorting in accordance with the values entered under 'Priorities'. The availability check is carried out for each individual schedule line.
Example for processing at schedule line level:
Sorting: Date (delivery date first schedule line) - document number -document item
Doc. cat. Doc. number Doc. item Doc. sched. line Del. date PO 4500000012 10 0001 26.01. PO 4500000025 20 0001 28.01. PO 4500000025 20 0002 02.02. PO 4500000012 10 0002 26.02.
Here you can see that each schedule line was sorted according to its delivery date. Note that this type of processing requires more runtime due to the individual checks and more frequent saving.
The results of rescheduling are saved, as long as the program was not started in simulation mode. When calling up from the 'Sales' area menu or when directly starting via the development environment, the iniator is informed via a dialog box that he has just started a process that changes data. He can then decide whether or not he wants to continue.
Checking procedure for stock transfer documents:
An availability check of stock transfer documents in rescheduling is carried out in accordance with the check carried out when manually creating a document. If, however, the required quantity for a schedule line is not available on a particular date and will not be ready until later, new schedule lines are created for the stock transfer purchase orders and scheduling agreements, containing the relevant data. New items are created in this case for stock transfer purchase order requirements. The total sum of schedule line quantities for a processed schedule line corresponds to the schedule line quantity of the original schedule line.
First example: Using a stock transfer purchase order item with a schedule line:
a) Status of item before rescheduling run:
Del. date PO quantity Confirmed quant Confirmed del. date 23.07. 50 items 0 items -
==> This now affects the stock/requirement situation:
- Goods issue is posted for the material in the delivering plant on the 23.07.
- A purchase order of 10 items was created for the material in the delivering plant. Delivery is expected on the 29.07.
b) Status of stock transfer purchase order item after rescheduling run:
Del. date PO quantity Confirmed quant Confirmed del. date 23.07. 40 items 40 items 23.07. 29.07. 10 items 10 items 29.07.
==> The first schedule line was changed in accordance with the results of the rescheduling availability check. Only 40 of the 50 original items could be delivered on the 23.07. Therefore, a new schedule line is created for the rest on the 29.07. for 10 confirmed items.
Second example: Same output situation as the above example.
==> There is now a change in the requirement/stock situation:
A purchase order for 10 items is created for the material in the delivering plant. Delivery is expected on the 29.07. A further purchase shows another 40 planned items on the 30.07.
Status of stock transfer purchase order item after rescheduling run:
Del. date PO quantity Confirmed quant Confirmed del. date 29.07. 10 items 10 items 29.07. 30.07. 40 items 40 items 30.07.
==> The first schedule line was changed in accordance with the result of the availability check for rescheduling. The original delivery date is set to the date confirmed in the ATP check. A new schedule line is created for the remaining 40 items, that are available on the 30.07.
Note:
Any set fixed delivery date and quantity indicators and creation indicators for schedule lines or items are 'inherited' by newly created schedule lines. Assuming that the original schedule line was fixed in the above example (since it is created manually), this indicator is also set for the newly created schedule line.
If shipping scheduling is activated for a stock transfer document type, this is also implemented for newly created schedule lines, with the exception of route schedule determination. This means that in the current version of the program no route schedule has been determined for a schedule line containing a route schedule for which new schedule lines may need to be created.
The results of the run are issued in the form of a list, which is also saved, so that the results can be controlled at a later date. This is done using the function 'Evaluate rescheduling', but it is only a good idea to do this after the first rescheduling has taken place. You can restrict selection requirements but these can however affect the runtime. You can use this function to analyze the saved list until the next rescheduling run, which writes over the result. If you start rescheduling in the background, a spool file with the result list referred to will be created in the corresponding setting. You can see this in spool management.
Output
A list of changed documents, a list of documents in which an error occurred during processing and as a result were not changed, can be called up via the menu 'Edit - Error log'. If in a subsequent evaluation a restricted selection is carried out, a note appears at the end of the list to say that not all document items are displayed.
You can set the scope of the list under the menu option 'List' in the list display. You can view improvements, deteriorations and the whole list. Before the documents can be included in one or either of the restricted lists, the date or quantity has to have changed so that the item can be contained in both the list of improved or deteriorated documents.
You can use the interface for changing transactions and the order list to navigate. Use 'Back' to exit the list and 'New selection' to return to the selection screen.
Recommendation
You should only start this program occasionally and use very restricted selectin criteria during working hours as it requires enormous system resources.
Note
The columns for 'New date' and 'New confirmed qty' only contain entries if the dates or quantities have changed.
As the system only runs the change check (dates/quantities) per line in the original list, an item whose backlog has increased in the list of improvements. This occurs, for example, if the whole quantity can be delivered at once but at a later date. In this situation, the system determines an increase for the line when it compares quantities.
