Purpose

Automatic transfer of rental unit master data from another system into the SAP System using direct input.

Process

The data transfer file (flat file/sequential file) contains the data from the legacy system in a certain format that is an SAP-compatible format . This is a prerequisite for a successful data transfer. The principle of transfer in the system can be seen from the following diagram:

Rental unit master records is transferred in the following steps:

Identify the relevant fields

The screens in the system are transaction-specific and process-specific. This means that the status of a field is influenced by certain factors and data combinations as well as being influenced by certain functions. A field can have the following statuses:

Entry required (required field)

Entry possible (optional field)

Entry is not possible (display field)

Hidden

Check the data extraction from the legacy system and which fields have to be filled by executing the SAP transaction for the rental unit.

Analyse transfer structure

The rental unit has the following transfer structures which define the possible fields:

Master record rental unit

Apportionment unit

Area

Room

Cost center

Condition header

Condition item

Owner

Partner

Address

User-defined field

Connection to PS

Connection to PM

Fixtures and fittings characteristics

Example: Create Sample Data Transfer File ( test data transfer)

SAP recommends that you

Request the LSM Workbench for simplifying the generation of sequential files

Test the transfer procedure before the actual transfer from the legacy system

Write and test conversion program

Extract the data that you have to transfer into the system by using a customer-specific program or the LSM Workbench. Write the data in the required order into the sequential file. Before you extract the data, you should be familiar with the control parameters of the rental agreement master data maintenance.

You place the SAP-specific data such as transaction codes in the sequential file as well as the data to be transferred. To generate the sequential file for the direct input process, you have to compare the SAP system structure with the structure of your old system. You might have to add to your data or change the format/length of the field contents.

You can generate a sequential file with report RFVIMEGN (see the report documentation).

Create a master record with the rental unit transactions and generate a sequential file from it. In this way, you can clearly see with what values the fields have to be filled.

You make the data transfer with report RFVIMEDI (see the report documentation).

The user who starts the data transfer must be authorized for rental unit master data authorization. These authorizations are checked during data import.

The system makes the same checks during automatic data transfer as it does during manual data entry. The same error messages and warnings are issued; data is posted in the same way and updated in the database. If an error occurs during import, an error log is written.

This error file can be processed and read any number of times until all errors have been rectified.

You can edit and display the contents of the sequential file in a structured form with report RFVIMESH. This report helps you to locate errors in the sequential file and rectify them (see the report documentation).

Once you are familiar with the transfer principle, do steps 1-3 for your own original data.

You can find all relevant transactions for the rental unit master data transfer in Customizing for Real Estate with the relevant documentation: Real Estate → Production Startup Preparation.

Result

Error-free rental unit master records are transferred to the system.
