DSO - Direct Update - Insert

Hi Guys,

I wrote ABAP programm to update DSO.

It looks like as follow:

            ....

            ls_wlb_dso-/bic/g_unit = lf_p_param_cu.
            ls_wlb_dso-/bic/g_wlb_t = lf_text.

            MODIFY /bic/ag_div_o300 FROM ls_wlb_dso.

If I put into the lf_text field the string with capital letter like: 'TEST' everything works fine, but if I use normal letter: 'test' the data are not correctly store in the table.

Additionally I get in the query the following error message:

Do you have maybe any idea why?

Best Regards

Erwin
