SAP FPM Form Repeater UIBB dynamic programming.

Hi Experts,

I want to know how to change the form repeaters input fields length/Data type in form repeater UIBB dynamically. I have came across ET_FIELD_DESCRIPTION exporting parameter in form repeater interface-GET_DEFINITION method. In this exporting table there is a column called field length. I tried creating technical field in CT_DATA(within UI structure) and mapped the field name in GET_DEFINITION. And filled data for the column in GET_DATA. But the length is not reflecting in UI.

Am I missing something or some steps...!?

There was an another field called READ_ONLY_REF this worked perfectly fine for me.

System in use:

Thanks In Advance...

Please let me know I you need further details on this.
