Screen field value wasn't passed into search help import parameter

[EricYu0912]

Hi experts, 

For the following material batch search help, I can't get material number (MATNR), which was input in the screen, in the search help function exit. What could be reason of the issue? 

Field MATNR and CHARG (batch) are in the same screen structure.

Regards,

Eric

The root cause has been found. The search help binding name was wrong.
