Hi Shaik,
You can check the iterator class of the table. I strongly doubt that you are using a custom iterator class in your page. The class name you can find in u'r htm page. Code will be something like,
DATA: ZCL_THTMLB_FORM_IERATOR_SAMPLE.
CREATE OBJECT lr_iterator
EXPORTING iv_context_node = BTOPPORTH(context node name).
cl_chtmlb_config=>set_iterator( lr_iterator ).
Now put a breakpoint in class ZCL_THTMLB_FORM_IERATOR_SAMPLE method RENDER_CELL_START. You will see which field is having the mismatch issue.
If the error is not showing for all users, you can run the report BSP_DLC_DELETE_PERSONALIZATION to delete the personalization and see.
Thanks,
Faisal
