Y9030005: EXPORT of Data to table INDX

A small data base application with “IMPORT”, “EXPORT” and “DELETE”. The following 3 reports belong together. It should be demonstrated that heterogeneous data e.g. from a subsystem, can be relatively simple transferred to the R/3(r) system and later administrated there.

Any data list (e.g. addresses, birthday, hobbies and so forth) is complemented with date and time and saved as a data cluster in the table INDX with the command “EXPORT …” . Through “IMPORT …” the data saved in the INDX are selected and displayed again. Here, any period of time can be selected on the basis of the time axis (DATE, TIME). Via “DELETE …” the possibility exists to delete no more required data from the respective cluster. The examples only use the field “TEXT1” as “useful information”, any other data contents can be used alternatively here in the reports.

Parameters:
The total keyword in the INDX consists of 22 bytes (in release 3.1), where 20 bytes are used. A time window can be used for the precise selection of an up/to area:

    • MOVE P_KDNR TO KEY_VON+0(6).    “e.g. customer number
    • MOVE P_DATVON TO KEY_VON+6(8).  “Date of
    • MOVE P_TIMVON TO KEY_VON+14(6). “Time of
