ABAP Code for Backup the entire table data in the application server

Former Member — Fri, 18 Jul 2008 13:36:10 GMT

Hello Friends,

I have to create the table data Backup and Store the entire table data in the application server and also be able to restore the data back if needed.

this should be dynamic program for any table based on the table name given on the application server.. I have developed a program for this but its having problems with the Quantity, amount. Its not writing it correctly at the application level.

ANy Suggestions on this.

Below is the program for this.

Thanks,

Ster.

Hello Ster,

I think u r passing the quantity fields directly to application server. U should convert those into character then only it will take them and print them properly.

I'd suggest you look at the options on OPEN DATASET. I think you want to open the datasets in BINARY mode. Numeric data is stored (most often) as Binary Coded Decimal.

I really hope this is just an exercise, and that you'd NEVER run this on a real system!

I have developed a program for this but its having problems with the Quantity, amount. Its not writing it correctly at the application level.

Quantities, Currencies are not trnasferred to Application server. Before Transfering the Quantities and Amounts you have to convert them to Character format and then Transfer the data.

THanks All for all ur suggestions.

I was wondering how would I change them to the CHAR format as everything here is dynamic. Please suggest.

former_member194669 — Fri, 18 Jul 2008 13:57:31 GMT

Ster,

You need to convert the quantity field content into character format.

in your form BACKUP you need to convert like the following


LOOP AT <f_table_data1> ASSIGNING <f_wa_table_data1>.

LOOP AT i_fcat INTO l_wa_fcat.

          if l_wa_fcat-inttype eq 'P'.
            assign component l_wa_fcat-fieldname
                of structure <f_wa_table_data1> to <comp>
                type     fields_int-type
                decimals fields_int-decimals.
          else.
            assign component l_wa_fcat-fieldname
                of structure <f_wa_table_data1> to <comp>
                type     fields_int-type.
          endif.
    " Move <com> to a new table and use this table for download

I am struggling a bit to get this.

there is a syntax error,

Field "FIELDS_INT-TYPE" is unknown. It is neither in one of thespecified tables nor defined by a "DATA" statement.

Again you have asked to move to a diffrent table. What is that table and how to build it.

It writes now.

But there is one more concern.

The file on the app server does not have all the data. I mean it has all the rows but for each row some of the fields have disappeared.

Any Suggestions.

However I have made samlll changes to the code.

I have writted the addition datatement after the write statement and also have included the decimals in addition.
