hi,
this can done through rescheduling. Pl. check the notes below :
Rescheduling Sales Documents
The following functions exist for rescheduling:
Performing rescheduling
Evaluating rescheduling
Performing Rescheduling
When rescheduling is performed, the open sales document items in the item index for the material are processed. The items found by this process are sorted according to the criteria delivery priority, date, document number, and item number and forwarded to the availability check. The results are then saved.
Note the following constraint with regard to rescheduling and the combination of availability check against ATP logic and the check against product allocations. If you use the availability check against ATP logic and the check against product allocations, dates and quantities can only be redistributed in a restricted way. In SAP R/3 there is no information on which product allocation quantities in which periods are assigned to the sales order. The product allocation assignment is therefore missing. For that reason, when several sales orders are rescheduled, only the product allocation quantity of the sales order being checked each time can be released. If the product allocation quantities of all other periods are already reserved, the sales order to be checked cannot be confirmed at any other time.
Simulating Rescheduling
You can carry out rescheduling in simulation mode. This can show you what would happen if you were to carry out rescheduling. The results are not saved, however.
It only makes sense to carry out this function if you only want to check a very limited selection of documents.
Credit Limit Block
In the case of a credit limit block in the order header (delivery block reason '01'), a credit limit control is performed before the availability check if the special type of block affects requirements. The document can then only be processed further once the customer involved becomes creditworthy again. The results of the run are issued as a list and stored temporarily. They can be evaluated with the function ‘Evaluate rescheduling’.
Selection Report
There is a report in the standard system, that selects the documents relevant for rescheduling. If you want to create you own reports, contact your SAP consultant.
Processing Parameters
You can define the scope of the check using the parameter 'Unconfirmed documents required'. If this parameter is set, at least one document for this material must be unconfirmed if all documents for this material are to be included in the availability check. Otherwise (no unconfirmed documents exist for a material), no document for this material is included in the availability check.
You can define that the delivery date entered when an order is created is used as a sorting criterion for the availability check using the parameter 'Sorting criterion deliv.date'. If this parameter is set, all orders of the same priority are sorted according to delivery date. Otherwise, sorting is performed by document creation date.
Display Criteria
The display criteria for the list can be defined under the menu option ‘List'. Improvements, deteriorations, and the complete list are the options. To be included in one of the two limited lists, an item must have undergone a date or quantity change. This means that an item can be included in both the improvements list and the deteriorations list.
There is only an entry in the columns 'New date' and 'New confirmed qty’ if the fields 'Old date' and/or 'Old confirmed qty' have been changed. As the check for changes (date/quantity) is only performed by line in the original list, it is possible that an item which has become more overdue is included in the list of improvements. This occurs if, for example, the entire quantity can be delivered in one delivery but at a later date, as a comparison of quantities for this line reveals an increase. You must make sure that all required sales and distribution document types which are to be included in the item index have been correctly configured in Customizing. This means the item indexes for all SD document types which are to be included in the availability check must be activated.
Evaluating Rescheduling
The evaluation function uses the list created by the function ‘Execute rescheduling’ as a work list. The outcome of the run is displayed in the form of a list.
Display Criteria
The display criteria for the list can be defined under the menu option ‘List'. The options are improvements, deteriorations, and the complete list.
There is only an entry in the columns 'New date' and 'New confirmed qty’ if the fields 'Old date' and/or 'Old confirmed qty' have been changed.
Pl reward if it helps.
Thanks
