Do ur scenario involve appending multiple entries to the same file? If yes, u may maintain a table in any database or SAP system wherein u may store the key field name each time u process a record. Next time when the same key occurs, before inserting, it will perform a RFC/JDBC lookup in mapping to know if that record has already been inserted before. If not then u may proceed with inserting the record.
by using delete adjusant duplicate entries in ABAP.
i can able to avoid it.
but, i request standard function in XI to avoid entries before message mapping( i mean supressing the entries) or using file adapter configuation parameters.
The message mapping functions and udf are only applicable on one current payload at a time. They cannot store earlier data. U should access a system (via lookup or any alternate) to find out whether such an entry has already been made or not.
Choose ABAP mapping and write adjacent duplicate statement automatically duplicate will be avoid, currently we don't have standard function to stop duplication, depending on requirement developing UDF only
