ABAP Refresh Selection Screen

[Former Member]

Hi Gurus,

I'm using selection screen parameters to accept 2 columns of material numbers and quantities.  There are multiple rows on the screen.

When editing the values with "AT SELECTION-SCREEN ON field" it will stop at the field in question to perform the edit.  However, upon fixing the error I would

like for the screen to re-fresh with everything entered thus far.  Perhaps I have entered a material and quantity and the material is incorrect.  I wuld like to fix the

material (which is working), but to then refresh the screen in case I need to change the quantity as well.  Any help would be appreciated.

Thanks,

Mike

check this post http://scn.sap.com/thread/1860208 to save the selection screen parameters entered. This will give you a backup.... after refresh you can use the values provided by the FM

Hi Michael,

Why don't you use AT SELECTION-SCREEN event instead of AT SELECTION-SCREEN ON event? In this way you won't face this issue and you can put all the validation under one event.

Rudra.....Using AT SELECTION-SCREEN works fine for what I'm doing, but I can't get the cursor to remain on a field that has an error.  The message will say "Invalid material", but doesn't remain on that field for the user to correct it.  I have tried SET CURSOR, but it doesn't seem to work.  Can you help ?.

Hi Michael,

SET Cursor field should work. I just checked it. It works like a charm. Please check your syntax as it does not give syntax error if you write it in a wrong way.

It should be like this

set CURSOR FIELD 'P_MATNR'. "P_MATNR is the parameter name for Material

Or if you are using select options then it should be

set CURSOR FIELD 'S_MATNR-LOW'.

Please note the name of the fieldl has to be written withing single quotes and should be in uppercase. Otherwise it will not work.

Hope it helps.
