how to modify results using this bapi: BAPI_INSPOPER_RECORDRESULTS

Dear experts,

We need your help regarding a problem we have to modify results using bapi: BAPI_INSPOPER_RECORDRESULTS

The first time we enter results it works great, but later we need to include adjustments to the same results and it returns the errors:

Q5 026 Defects occured during confirmation

QI 139  Single value &1 was not copied for confirmation number &2

We are populating this parameters:

char_results-insplot  

char_results-inspoper 

char_results-inspchar 

char_results-closed   

char_results-evaluated

char_results-evaluation

single_results-insplot      

single_results-inspoper     

single_results-inspchar     

single_results-inspector    

single_results-insp_date    

single_results-insp_time    

single_results-res_no       

single_results-ext_no       

single_results-res_value    

single_results-original_input

single_results-res_valuat 

And calling the bapi like this:

CALL FUNCTION 'BAPI_INSPOPER_RECORDRESULTS'
      EXPORTING
        insplot        = gv_prueflos
        inspoper       = lc_inspoper
      IMPORTING
        return         = ls_return
      TABLES
        char_results   = lt_char_results
        single_results = lt_single_results

I tried changing the sample size, but instead of replacing it instead added new values.

I thank your attention in advance hoping you can help us.

best regards,

Pedro Martinez
