method implementation using ABAP objects

[Former Member]

hi folks,

I am impelementing a method using one of the parameters, which is a internal table taken as an import parameter.

I am using the field symbols to <b>modify</b> the table data but it is not working.

method IF_EX_PT_ABS_ATT_COUNTRY~CALCULATE_COUNTRY.

The method CALCULATE_COUNTRY has a parameter

TIMES_PER_DAY Importing TYPE PTM_TIMES_PER_DAY.

This is the table tha t retrieves the data for the Absence infotype 2001 for an employee and has the field

ABRST value populated.

I need to clear the value for this field and update the table 'TIMES_PER_DAY' before it populates the infotype record.

Hence I am writing the code in its method by calling the parameter.

here is the piece of code....

FIELD-SYMBOLS: <F1> TYPE PTM_TIMES_PER_DAY.

loop at times_per_day into <F1> where datum eq begda.

clear <F1>-abrst.

ASSIGN <F1> to times_per_day. ****ERROR

endloop.

endmethod.

I know the error is because trying to assign the <F1> field symbol to internal table.

But how can I do that ultimately I need to update the internal table 'times_per_day '

ALSO TRIED THIS....

data: w_tab type PTM_TIMES_PER_DAY.

loop at times_per_day into w_tab where datum eq begda.

CLEAR w_tab-abrst.

modify times_per_day from w_tab transporting abrst.

endloop.

It gave an error saying the table 'times_per_day' cannot be changed.

I hope you got what I am trying to achieve here... any leads or guidelines will be really helpful,

Thanks

Is this table part of the IMPORT PARAMETERS list. If that is the case you cannot change the table.

It should be in the EXPORTING parametes to change.

We cannot change importing parameters. We can only do it when it is in changing / exporting parameters.

Yes, I got it, there is an exporting parameter, there is nothing in that table. as and when I enter the records for 2001, it is this table that gets populated.

Waht can i do here?

Thanks for your reply.
