Validating flat file

Former Member — Thu, 10 Jul 2008 04:33:07 GMT

Hi folks,

I have to validate the entris in my flat file before passing it to the BDC.I have a RATE field as 5th field. How to check whther the 5th field contains valid RATE values.We cannot check the entries from the table. Becaus we can give even new entries here. I think we have to check the data type. Could any body let me know, how to check this..Thansk in advance..

Ram.

Hi Ram,

Design a Selection screen which has a table control, Put the fields onto it. And also place some buttons like INSERT , DELETE EXIT on the selection screen.

Where INSERT is to INSERT the records into the database.

DELETE is to DELETE the record which has wrong entry.

EXIT is to exit from the screen.

Use the Call transaction method with MODE as 'A' and check the records. and then insert into the database. This solves the issue.

Regards,

Swapna.

hi when you get the records from flat file and split and put into ur internal table structure... validate that 5th field before appending into the internal table..

split wa_flat into

wa_f1 wa_f2 wa_f3...

at '|'.

validate 5th record here...

append wa to itab.

Hi,

U have to check at flat file level only.... that is down by functional consultants.. As an abaper we need to use that flat file only.. and one more thing if yo uwant to check whether the field holds the data/value that can be down at internal table level...

Hi,

Validating rate means wat do u mean?

If ur trying to check whether it is decimal or not u can use this piece of code...

REPORT ztest2 . "IDES Textpool

DATA rate(11) TYPE c ."p DECIMALS 4.

DATA rate1(12) TYPE c." p DECIMALS 4.

rate1 = '.0123456789'.

rate = '10.90'.

IF rate CO

rate1.

WRITE rate.

ELSE.

WRITE 'error'.

ENDIF.

replace rate with some..'a123h' & check result...

Hope this will be useful
