Cumulative Transmission of Differences R/3 -> Cumulative Transmission of Differences R/3 ->
The aim of cumulative transmissions from the R/3 System is to accumulate inventory differences (or even goods movements) and then to transmit them all at once to the R/2 System.
There are three relevant tables in the R/3 System:
Control of individual processing: "Movement Type Decentral.MM-WM
® Host Activity"Control of multiple processing: "Accumulated Messages for the Host (R/2)"
R/3 movement types
You define these tables using the Warehouse Management IMG. To maintain the first two tables, choose Interfaces ® Define decentralized link to R/2 and then the appropriate table from the list of objects. To maintain R/3 movement types, choose Activities ® Transfers ® Movement types.
General Process
Quants are collected in an interim storage area.
The ABAP RLDLVS10 reads the data about the quants and creates one transfer order per quant.
The transfer order decreases the quantity in the interim storage area and creates a communication document that is sent to the R/2 System over the normal CPI-C interface.
The following factors regarding negative and positive quants in the interim storage area apply:
Negative Quant in the Interim Storage Area
Indicates (a difference for) a goods receipt into the warehouse (resulting from a transfer order for a putaway).
From: the interim storage area (for cumulative transfers) (-)
To: a storage bin in the warehouse (+)
Positive Quant in the Interim Storage Area
Indicates a goods issue from the warehouse (resulting from a transfer order for a pick).
From: a storage bin in the warehouse (-)
To: the interim storage area (+)
Posting Control
To control the postings for the interim storage area, there are two possibilities:
Easy Method
Define a movement type for the goods movement, but do not include it in the table for "Control of individual processes". In the movement type itself, you must define to which storage type the goods are to be sent.
Material-Dependent Method
For all goods movements, the data is transferred directly to the R/2 host unless a specific material has been defined otherwise.
For this process, the movement type must be in the table for "Control of individual processes". In that table, depending upon the direction of movement, you enter 2 in the Source items or Destination items fields accordingly. The system still looks in the material master record and creates communication documents only for materials where the Message to IM check box is marked. For more information about the control of individual processes table, see
Sending Communication Documents from R/3 to R/2.Sending the Quants to Inventory Management
To transmit the quants to Inventory Management in the R/2 System, you use the report RLDLVS10 as follows:
Choose System
® Services ® Reporting from any menu bar and choose ENTER .Enter RLDLVS10 in the Program field and choose Execute.
Enter the warehouse number and storage type for the accumulation interim storage area and choose List
® Clear online foreground or List ® Clear online background.For each quant, the system creates a transfer order that clears the interim storage area. The creation of the transfer order results in the creation of a communication document that is then transmitted to the R/2 System.
How are the Transfer Orders Created?
The movement type in the table "Control of multiple processes" is used to create the transfer orders when report RLDLVS10 is executed.
The table below illustrates how this table can be set up to control multiple processing for differences.

To define these movement types see Activities
® Transfers ® Movement types in the Warehouse Management IMG documentation.For negative quants, the movement type creates a transfer order for a putaway. The movement type "-" (minus) unburdens, so to speak, the source item in the transfer order.
For positive quants, the movement type creates a transfer order for a pick. The movement type "+" (plus) unburdens, so to speak, the destination item in the transfer order.
Where do the transfer orders get their data?
Since the ABAP reads the interim storage area, the correct data (including the requirement tracking number) is automatically retrieved for each of the quants.
