DYNPRO_FIELD_CONVERSION
lowData Conversion Failed When Moving Value to Screen Field
Module: ABAP / Dynpro
What this means
DYNPRO_FIELD_CONVERSION occurs when a value being transferred to or from a screen (dynpro) field cannot be converted to the expected data type. This typically occurs when a program-level variable and the corresponding screen field element have incompatible types, and the automatic screen-to-program conversion fails. Common scenarios: a numeric screen field receiving a value with non-numeric characters; a date field receiving a value in the wrong format; or a custom screen field whose type definition in Screen Painter (SE51) does not match the ABAP data type in the module pool.
Check ST22 for the screen number and field name. Open SE51 and check the field attributes — type, length, and conversion exit. Compare with the corresponding program variable. Add a conversion routine or validate the value before it reaches the screen. If using a conversion exit (ALPHA, etc.), ensure the input value is in the correct internal format before the screen is populated.
