Periodic Data Transfer

Use

You can use the program /SAPDMC/SAP_LSMW_INTERFACE to transfer data to the SAP system periodically rather than once only.

Integration

/SAPDMC/SAP_LSMW_INTERFACE is an additional program of the LSMW.

Prerequisites

• The LSMW object has been created completely and tested.

• The "source application" periodically provides one or several files on the application server.

• The LSMW object does not access files stored on the front end.

• You have set the indicator for periodic data transfer in step Maintain Object Attributes.

Features

The periodic data transfer is carried out in the following steps:

1. Importing Data

2. Converting Data

3. Importing Data

Activities

Schedule the program /SAPDMC/SAP_LSMW_INTERFACE according to your requirements. To do this, create a variant and use transaction SM36 ( System  Services  Jobs  Define Job) to create a job.

• The main program for the periodic transfer of data only runs if the specified flag file exists.

• Once the transfer of data has been completed, the main program deletes the flag file.

• The application that provides the input file(s) must be compatible with this flag file: Before new files are generated, a check is made to see whether the flag file exists. If so, the program stops. Otherwise, the files are generated and the flag file is created.
