Define
Decentralized Link to R/2
Various definitions must be entered both in the
R/2 and R/3 systems to facilitate communication between a central R/2 System
and a decentralized Warehouse Management system (R/3).
In this step you define the necessary R/3
parameters.
Requirements
If the R/2 and R/3 Systems are intended to
communicate with each other, you must install the standard interface
CPI-C.
Activities
1. Install the
necessary CPI-C basis and application components.
2. Activate the
warehouse number (field Decentralized
warehouse) that is to be installed as a decentralized Warehouse
Management system.
3. Number range
interval for allocating communication documents.
Here you cannot
define a new number interval. Number range 01 is standard.
You can only reset the number range.
Check the number
range (number range object "Dec. communication") for the communication
documents.
4. With interim
storage postings in the Decentralized Warehouse Management system, you can
have the system determine the
interim storage bin to which the posting is to be made as
follows:
a) The interim
storage bin is always defined as a dynamic storage bin, that is, the same as
the R/2 document number.
b) The interim
storage bin is determined just as in the integrated Warehouse Management
system by movement type definition.
The default is to use the first type (a) of interim storage type search. The
other type (b) must be activated at the warehouse number level.
5. For certain
business transactions (for example, create material masters, postings that
change stocks) in the Materials Mangement system (linking R/2 -> R/3),
mails can be sent.
The following are
the individual business transactions (record types) that can be
assigned:
- WM03 Delivery notes (R/2-Rel. 4.3)
- WM04 Delivery note appendices (R/2-Rel.
4.3)
- WM05 Material master maintenance
- **** all business transactions
Assign the different
record types to the individuals responsible.
6. Within the
R/2 -> R/3 connection, it is possible to activate different logging
functions.
The system first searches for an exact table entry match (warehouse number).
If no suitable entry is found, the system then searches for warehouse number
"***".
The following
parameters are available for you to use:
- Logging of the communication records
transferred from R/2
- Mail to the person responsible after creating
a material master
- Logging of CPI-C or logical errors
- Parameters for ouput control (for example,
printing time, printer assignment)
These logging
functions may make an error analysis easier during project implementation.
You do not have to activate all functions in production.
Activate the
necessary logging functions.
All the following activities must be carried
out for the R/3 -> R/2 link:
7. Various
business transactions (for example, goods receipt from production) generate
communication documents for the R/2 System. These communication documents are
stored in a queue. Using this technique, data can be transferred between R/3
and R/2 at different times.
Define the necessary
queues and activate them.
8. The
Warehouse Management system communicates via communication numbers with the
R/2 System. Define the communication numbers and assign them to the queue
names.
9. During
communication from R/3 to R/2, communication control is affected by a
transaction key. Assign the transaction keys to the WM movement types that are
to initiate a posting in the R/2 system.
10. In the
Warehouse Management system, it is not always appropriate to notify the
Inventory Mangement system of each individual posting immediately (for
example, difference postings, GR from production). These business transactions
can be sent to the R/2 System cumulatively.
Define the storage types and movement types which should trigger a message to
the Inventory Management system.
Further
Notes
The SAP Systems communicate with each other via
the standard interface
CPI-C . For information as to which host computer types this
interface is suitable for and how the communication works from a technical
point of view, refer to the SAP information brochures.
In the R/3 documentation, refer to the chapter
on "Decentralized Warehouse Management".
