Value Help Leading Zeros

Hi Folks,

again another difficult question.

We got an inputfield type matnr with a valuehelp S_MAT1 an a OUTPUT_002 conversion exit.

Now we developed a new value help which is also easy selecting from mara.

BUT the returned value is displayed with leading zeros AND our conversion Exit is ignored by the system.

We tried to use our serchhelp in a Collective Search Help and there it worked with the exit.

The Problem is not the Exit. In Standard Gui everything works fine with the normal, our, and the new collective search help.

But in WD it doesn't work.

Some Ideas ?

Thanks & Best Regards
