Private methods Importing parameter cannot be changed error

Former Member — Wed, 15 Sep 2010 01:38:16 GMT

Hi Guys,

I have this scenario where I have a private method inside a class which is having an error "Field SAPMF02K cannot be changed".

here is the code for the private method call.

call method create_bdc_dynpro

importing IM_PROGRAM = 'SAPMF02K'

IM_DYNPRO = '0100'.

code of the method

data: wa_bdcdata type bdcdata.

CLEAR wa_bdcdata.

wa_bdcdata-program = im_program.

wa_bdcdata-dynpro = im_dynpro.

wa_bdcdata-dynbegin = at_true.

APPEND wa_bdcdata to at_bdcdata.

Hope you can help

Thanks!

Howdy,

I think you have your importing/exporting the wrong way round.

The method call should be:

call method create_bdc_dynpro

exporting IM_PROGRAM = 'SAPMF02K'

IM_DYNPRO = '0100'.

And of course in the method definition they should be importing parameters.

Cheers

Alex

Thanks Alex. That solved the problem

Is this also the case for Public Methods?

Howdy,

Yep that applies regardless of the visibility.

Cheers
