[Former Member]

Hi expert,

I am a beginer in table control.

I have a problem.

I create a table control in that I use a search help for a column. Everything is normal if I enter a value into search help value and save .

There are two situation:

1. In the first time I save this document without value in this column. After that,I reopen this document and enter value by use F4-> a error .

2.I save table control with value in seach help value. But when I change value in search help, a same error act.

Immediately, I debug and see after pass POV, next PBO : after LOOP table control 2 times because in my table control have 2 record, a error happen.

I thank you so much with ur help.

This error:

DYNPRO_FIELD_CONVERSION

Short text

Conversion error

What happened?

The current screen processing action was terminated since a situation

occurred where the application could not continue.

This is probably due to an error in the ABAP program or in the current

screen.

Error analysis

The program has been interrupted and cannot resume.

Program "SAPMZ_PM03" attempted to display fields on screen 0200.

An error occurred during the conversion of this data.

Hi,

Please check if you have done the following,

=> Have you looped at the internal table with respect to the table control

LOOP at itab WITH CONTROL TABLECONTROL.

ENDLOOP.

=>Check if you have done it both in the PBO and the PAI.

=> Check if your fields in the table control and the fields that you have been using in the program match.

=> Have you modified your database table fields and not regenerated the Table Maintanence Generator (TMG) after that? The database table will only contain the older fields if you havent regenerated the TMG and activated it.

Hi,

I cant explain this error to solve it.

Error is just happen when change value in this field-field use search help-only on the first line in table control.

If the first line isnt change, I can change in the second line that not error.

When debug , in error, I see PBO TC200-current_line cant increase . It stop with current line in table control but in my table control , I put mode open line .

What is Table Maintanence Generator ? How to do it?

Thanks alot.
