Converting the data back to table using SAP FM RFC_READ_TABLE

This is very simple and you can write a code as below. This code works when you only have character fields in the table ?

Example

Here's how to use the RFC_READ_TABLE function module to convert data back to a table structure ?

DATA: lt_options TYPE TABLE OF rfc_db_opt,
      lt_fields  TYPE TABLE OF rfc_db_fld,
      lt_entries TYPE TABLE OF dpr_pha_type.

CALL FUNCTION 'RFC_READ_TABLE'
  DESTINATION 'Y58CLNT800'
  EXPORTING
    query_table = 'DPR_PHA_TYPE'
  TABLES
    options     = lt_options
    fields      = lt_fields
    data        = lt_entries.

In this example:

• lt_options contains WHERE conditions for filtering data
• lt_fields specifies which fields to retrieve from the table
• lt_entries stores the retrieved table data
• DESTINATION specifies the target SAP system
• query_table defines the table name to read from

Note: This approach works best when dealing with character fields. For tables containing numeric or date fields, additional data type conversion may be required to properly format the retrieved data.

Conclusion

The RFC_READ_TABLE function module provides a straightforward method to convert and retrieve table data remotely in SAP systems. This technique is particularly effective for character-based table structures and forms the foundation for remote data access operations.
